[git commit] buildsys: Fix setting LIBGCC

[Bernhard Reutner-Fischer]

commit: http://git.uclibc.org/uClibc/commit/?id=5f374c1fe85a1da95c15a5cac217f8ab762ce6dd
branch: http://git.uclibc.org/uClibc/commit/?id=refs/heads/master

We were ending up with multiple entries in LIBGCC for recursive child
make instances, avoid that.
