Hi,
This patch fixes recent regressions in libgomp testsuite:
https://gcc.gnu.org/ml/gcc-regression/2014-11/msg00343.html
They are reproducible only with ld from trunk, ld 2.24 works fine.
When GCC emits sections with offload IR, it should not emit "__gnu_lto_slim"
symbol, otherwise linker plugin tries to compile LTO IR, which is not present.
Bootstrap and regtesting on x86_64-linux using binutils 20141114 in progress.
OK for trunk when finished?
Thanks,
-- Ilya
