add linker option for LIB32 step on PowerPC64

[Alfredo Dal Ava Junior]

Hi all,


I'm working on having PowerPC64 using LLVM by default, but LLD support for 32 bit seems to be incomplete.  As workaround I'm using ld.bfd (2.17) for the LIB32 step.


I found no way to specify the linker for LIB32 step, so I created a variable called LIB32LD that I pass to "make buildworld". Apparently we'll have to make this workaround official, so I would like to know your thoughts about this approach or if you have some other idea to share.


Thanks,

Alfredo
