illumos gate

BIOS loader has limited memory for program binary, building it with PIC objects is wasting some amount of that memory.

Since BIOS loader is using 32-bit protected mode, it means, we need PIC and non-PIC objects for 32-bit build of loader itself and libficl/libstand libraries. 64-bit objects are only used to build EFI loader.
