gcc-4.6-spu: fatal error: -fuse-linker-plugin, but liblto_plugin.so not found

[Steve Langasek]

Binary package hint: gcc-4.6

newlib fails to build in oneiric with gcc-4.6, because gcc-4.6-spu appears to not work:

-fuse-linker-plugin is not passed on the commandline, so this seems to be a bug in gcc-4.6-spu itself.

Building with -fno-use-linker-plugin succeeds.

The build failure is reproducible also in Debian unstable.
