Even with 8c1fce46fc0 reverted libxul fails to link during
a profiledbuild. Normal build is fine.

with bfd:
/usr/lib/gcc/x86_64-pc-linux-gnu/4.7.0/../../../../x86_64-pc-linux-gnu/bin/ld:
../../layout/ipc/RenderFrameParent.o: relocation R_X86_64_PC32 against
undefined hidden symbol

making a shared object
/usr/lib/gcc/x86_64-pc-linux-gnu/4.7.0/../../../../x86_64-pc-linux-gnu/bin/ld:
final link failed: Bad value
