[OE-core] gold and -flto option

[Enrico Scholz]

Hi,

after enabling gold linker (ld-is-gold DISTRO_FEATURE), the '-flto
-fuse-linker-plugin' build options do not work anymore as with the old
bfd linker.  I am using the toolchain layer of oe-meta.

Is this expected or just some issue with our gcc?
