Jump to a label from inline assembly to C

I have a written piece of code in assembly and at some points of it, I want to jump to a label in C. So I have the following code (shortened version but still, I am having the same problem):

    #include <stdio.h>

    #define JE asm volatile("jmp end");
    int main(){
        printf("hi\n");
        JE
        printf("Invisible\n");
        end:
        printf("Visible\n");
        return 0;
    }

This code compiles, but there is no end label in the disassembled version of the code.

If I change the label name from end to any other thing (let's say l1, both in asm code(jmp l1) and in the C code), the compiler says that

    main.c:(.text+0x6b): undefined reference to `l1'
    collect2: error: ld returned 1 exit status
    Makefile:2: recipe for target 'main' failed
    make: *** [main] Error 1

I have tried different things(different length, different cases, upper, lower, etc.) and I think it only compiles with end label. And with end label, I am receiving segmentation fault because, there is no end label in the disassembled version.

Compiled with: gcc -O0 main.c -o main

Disassembled code:

    000000000000063a <main>:
     63a:   55                      push   %rbp
     63b:   48 89 e5                mov    %rsp,%rbp
     63e:   48 8d 3d af 00 00 00    lea    0xaf(%rip),%rdi        # 6f4 <_IO_stdin_used+0x4>
     645:   e8 c6 fe ff ff          callq  510 <puts@plt>
     64a:   e9 c9 09 20 00          jmpq   201018 <_end> # there is no _end label!
     64f:   48 8d 3d a1 00 00 00    lea    0xa1(%rip),%rdi        # 6f7 <_IO_stdin_used+0x7>
     656:   e8 b5 fe ff ff          callq  510 <puts@plt>
     65b:   48 8d 3d 9f 00 00 00    lea    0x9f(%rip),%rdi        # 701 <_IO_stdin_used+0x11>
     662:   e8 a9 fe ff ff          callq  510 <puts@plt>
     667:   b8 00 00 00 00          mov    $0x0,%eax
     66c:   5d                      pop    %rbp
     66d:   c3                      retq   
     66e:   66 90                   xchg   %ax,%ax

So, the questions are:

1. Am I doing something wrong? I have seen this kind of jumps (from assembly to C) in codes. I can provide example links.
2. Why the compiler/linker cannot find l1 but can find end?
