Summary:                    support tcc + rpath
Description: 
It would be nice to have tcc+rpath working in cmake.

Steps:
cd /tmp
$ cat l.c
int foo() { return 42; }
$ cat a.c
int main() { return foo(); }
$ tcc -shared -o libl.so l.c
$ tcc -o a a.c  -Wl,-rpath=/tmp -L/tmp -ll
$ ldd a
	linux-vdso.so.1 =>  (0x00007fffe4087000)
	libl.so => /tmp/libl.so (0x00007f8ecce68000)
	libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f8eccab8000)
	/lib64/ld-linux-x86-64.so.2 (0x00007f8ecce6c000)
$ readelf -d a

Watch out that tcc requires "-Wl,-rpath=" (not -Wl,-rpath
-Wl,<some_search_path>")
