linker claims library not found, strace shows it try to access valid path though

I am trying to cross-compile something for Android, so I am using a separate toolchain. There is a library that the linker is complaining it cannot find:

arm-eabi-gcc: fatal error: -fuse-linker-plugin, but liblto_plugin.so not found

The library definitely exists in this path:

$ ls -l /mnt/hgfs/Documents/thesis/android-wmon/core/os/prebuilts/gcc/linux-x86/arm/arm-eabi-4.6/libexec/gcc/arm-eabi/4.6.x-googletotal 70053-rwxr-xr-x 1 501 dialout 47040814 Oct  3 14:29 cc1-rwxr-xr-x 1 501 dialout 50903764 Oct  3 14:29 cc1plus-rwxr-xr-x 1 501 dialout   423914 Oct  3 14:29 collect2drwxr-xr-x 1 501 dialout      204 Oct  3 14:29 install-tools-rwxr-xr-x 1 501 dialout     1090 Oct  3 14:29 libfunction_reordering_plugin.lalrwxr-xr-x 1 501 dialout       38 Oct  3 14:29 libfunction_reordering_plugin.so -> libfunction_reordering_plugin.so.0.0.0lrwxr-xr-x 1 501 dialout       38 Oct  3 14:29 libfunction_reordering_plugin.so.0 ->  libfunction_reordering_plugin.so.0.0.0-rwxr-xr-x 1 501 dialout    89427 Oct  3 14:29 libfunction_reordering_plugin.so.0.0.0-rwxr-xr-x 1 501 dialout      994 Oct  3 14:29 liblto_plugin.lalrwxr-xr-x 1 501 dialout       22 Oct  3 14:29 liblto_plugin.so -> liblto_plugin.so.0.0.0lrwxr-xr-x 1 501 dialout       22 Oct  3 14:29 liblto_plugin.so.0 -> liblto_plugin.so.0.0.0-rwxr-xr-x 1 501 dialout   238575 Oct  3 14:29 liblto_plugin.so.0.0.0-rwxr-xr-x 1 501 dialout 44647203 Oct  3 14:29 lto1-rwxr-xr-x 1 501 dialout   114284 Oct  3 14:29 lto-wrapper

So, in my compile line I included "-L/mnt/hgfs/Documents/thesis/android-wmon/core/os/prebuilts/gcc/linux-x86/arm/arm-eabi-4.6/libexec/gcc/arm-eabi/4.6.x-google" and then specify "-lliblto_plugin" ... but I still continue to get this error.

Here is my entire line and error:

EDIT: Running strace along with the compile, I see the accesses to read the shared library that fail:

access("/mnt/hgfs/Documents/thesis/android-wmon/core/os/prebuilts/gcc/linux-x86/arm/arm-eabi-4.6/bin/../libexec/gcc/arm-eabi/4.6.x-google/liblto_plugin.so", R_OK) = -1 ENOENT (No such file or directory)access("/mnt/hgfs/Documents/thesis/android-wmon/core/os/prebuilts/gcc/linux-x86/arm/arm-eabi-4.6/bin/../libexec/gcc/liblto_plugin.so", R_OK) = -1 ENOENT (No such file or directory)access("/mnt/hgfs/Documents/thesis/android-wmon/core/os/prebuilts/gcc/linux-x86/arm/arm-eabi-4.6/bin/../lib/gcc/arm-eabi/4.6.x-google/../../../../arm-eabi/bin/arm-eabi/4.6.x-google/liblto_plugin.so", R_OK) = -1 ENOENT (No such file or directory)access("/mnt/hgfs/Documents/thesis/android-wmon/core/os/prebuilts/gcc/linux-x86/arm/arm-eabi-4.6/bin/../lib/gcc/arm-eabi/4.6.x-google/../../../../arm-eabi/bin/liblto_plugin.so", R_OK) = -1 ENOENT (No such file or directory)

But interestingly, the first path that it tries does in fact exist, but it is a link:

$ file /mnt/hgfs/Documents/thesis/android-wmon/core/os/prebuilts/gcc/linux-x86/arm/arm-eabi-4.6/bin/../libexec/gcc/arm-eabi/4.6.x-google/liblto_plugin.so /mnt/hgfs/Documents/thesis/android-wmon/core/os/prebuilts/gcc/linux-x86/arm/arm-eabi-4.6/bin/../libexec/gcc/arm-eabi/4.6.x-google/liblto_plugin.so: symbolic link to `liblto_plugin.so.0.0.0'

That link is also valid:

    $ ls -l /mnt/hgfs/Documents/thesis/android-wmon/core/os/prebuilts/gcc/linux-x86/arm/arm-eabi-4.6/bin/../libexec/gcc/arm-eabi/4.6.x-google/total 70053-rwxr-xr-x 1 501 dialout 47040814 Oct  3 14:29 cc1-rwxr-xr-x 1 501 dialout 50903764 Oct  3 14:29 cc1plus-rwxr-xr-x 1 501 dialout   423914 Oct  3 14:29 collect2drwxr-xr-x 1 501 dialout      204 Oct  3 14:29 install-tools-rwxr-xr-x 1 501 dialout     1090 Oct  3 14:29 libfunction_reordering_plugin.lalrwxr-xr-x 1 501 dialout       38 Oct  3 14:29 libfunction_reordering_plugin.so -> libfunction_reordering_plugin.so.0.0.0lrwxr-xr-x 1 501 dialout       38 Oct  3 14:29 libfunction_reordering_plugin.so.0 -> libfunction_reordering_plugin.so.0.0.0-rwxr-xr-x 1 501 dialout    89427 Oct  3 14:29 libfunction_reordering_plugin.so.0.0.0-rwxr-xr-x 1 501 dialout      994 Oct  3 14:29 liblto_plugin.lalrwxr-xr-x 1 501 dialout       22 Oct  3 14:29 liblto_plugin.so -> liblto_plugin.so.0.0.0lrwxr-xr-x 1 501 dialout       22 Oct  3 14:29 liblto_plugin.so.0 -> liblto_plugin.so.0.0.0-rwxr-xr-x 1 501 dialout   238575 Oct  3 14:29 liblto_plugin.so.0.0.0-rwxr-xr-x 1 501 dialout 44647203 Oct  3 14:29 lto1-rwxr-xr-x 1 501 dialout   114284 Oct  3 14:29 lto-wrapper

ANOTHER EDIT: If I go in to the directory containing the shared library and remove the link from liblto_plugin.so to liblto_plugin.so.0.0.0 and then "cp liblto_plugin.so.0.0.0 liblto_plugin.so" then it links properly and my program compiles. Why is it broken when this file is a link? (sorry, using "link" to refer to two different things here).
