klibc: fix build with GCC and -pie for mips, mips64, aarch64

Browse Source 
The MCONFIG makefiles for mips/mips64 do disable pic so we do not insist
linking it with -pie.

For aarch64 we have to readd the -Os optimization to avoid

 | usr/dash/shell.h:103:25: error:
 '-mgeneral-regs-only' is incompatible with floating-point argument

as committed (c296fb707a klibc: Pass Optimization with KLIBCOPTFLAGS)
but reverted (76bc58e932 klibc: Fix build with security flags) trying to
fix the i386 build (see ld.bfd: discarded output section: `.got.plt').
This latter issue was fixed for i386 passing -pie to the linker.
