mk/gcc.mk: define LD to bfd version by default

In some cases, ld is linked to gold version,
and it will cause compiling error for 32bit like following:

prebuilts/gcc/linux-x86/arm/arm-linux-androideabi-4.9/bin/arm-linux-androideabi-ld: fatal error: --sort-section=alignment: must take one of the following arguments: none, name

with the bfd version ld, there will be no such error reported.
