Why i got many error when running "make"?

I need pro devs for my problem. I installed a toolchain (linaro) for building android kernel. Then, I export the CROSS_COMPILE variable with :export CROSS_COMPILE=/root/toolchain64/bin/aarch64-linux-android-.Then I export the ARCH Variable :export ARCH=arm64. Now, its the problem. When I execute make clean && make mrproper, it say a error : aarch64-linux-android- : Command not found. I already insert it to $PATH variable, but it dont work. Then, i run the aarch64-linux-android-gcc directly. Then it says that I must installed python first. After that, I install python python3 python3-dev python-dev and it says many different errors.

root@localhost:-/samsung# make clean && make mrproperTraceback (most recent call last):  File "/root/toolchain64/bin/aarch64-linux-android-gcc", line 66, in <module>    main(sys.argv)  File "/root/toolchain64/bin/aarch64-linux-android-gcc", line 63, in main    cw.invoke_compiler()  File "/root/toolchain64/bin/aarch64-linux-android-gcc", line 58, in invoke_compiler    os.execv(self.argv0, self.execargs)OSError: [Errno 2] No such file or directory

Im stuck with this error. I try to change the folder's permission, but the result is same. (Sorry for my bad english).
