rG5b042fcbdff8: Disable PIE for powerpc bootloaders.
rG9da7cdecf101: Disable PIE for powerpc bootloaders.
rG3aa023643e9d: Disable PIE for powerpc bootloaders.

Summary

Bootloaders for powerpc are not built as position independent
code. Since bsd.prog.mk is used for building, when PIE is enabled,
the PIE flags are added and that causes the build to fail.
Adding MK_PIE=no stops bsd.prog.mk from adding PIE specific flags.

46	IMO a comment is warranted if there's something specific we can point out (such as the -mno-abicalls issue with MIPS) but otherwise it's not needed, MK_PIE=no is sufficiently self-explanatory.
