It does for MIPS/n32. n32 is a 32bit ABI for MIPS64, so a lib32->lib
symlink is required.

Again, this should also handle the MIPS64/n32 case where lib32 is
needed instead of lib or lib64

Thomas suggested to have new symbols like ARCH_NEEDS_LIB32 or
ARCH_NEEDS_LIB64 selected by architectures that need lib32->lib or
lib64->lib symlinks respectively.
