GCC 4.6.0 20110108 no longer fails with `-fuse-linker-plugin'. Still fails with
`-fno-use-linker-plugin'.

This is documented feature.
See "Hidden symbols used from non-link time objects now have to be explicitly
annotated with externally_visible when the linker plugin is not used." at
changes.html
W/o handling hidden visibility the "optimistic" way, we would need extra
attributes to make LTO effective w/o plugin on shared libs (since
-fwhole-program + externally_visible flag is not too handy there given that
most programs was decorated the other way arround with hidden visibilities).
