ovmf: avoid linking with gold

Linking with gold fails due to an internal error in gold. The ovmf
linker is gcc, which has a -fuse-ld=bfd option to choose the linker
which (for ovmf) is known to work.

Like the choice of the compilers, this is done in ovmf-native. To keep
that recipe independent of DISTRO_FEATURES, choosing bfd is done
unconditionally.
