I am trying to use gdc in [testing] and it fails:

gdc: fatal error: -fuse-linker-plugin, but liblto_plugin.so not found

I ran strace for gdc command and it shows it tries to find liblto in
the old version locations. It seems gdc statically compiled against
gcc and should be recompiled against 4.9 as well.
