    klibc: fix build with GCC and -pie for mips, mips64, aarch64
    
    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 (c296fb707ae3 klibc: Pass Optimization with KLIBCOPTFLAGS)
    but reverted (76bc58e9329 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.
