mklibs library optimization for all arches

From: Nitin A Kamble <[email protected]>

I tested this with poky-image-minimal and I see some disk space savings by
using the mklibs library optimizations. (76MB rootfs became 75MB)

The minimal poky image had 106 dynamically linked executables. And the
footprint savings will go up as number of dynamically linked executables in an image decrease.

I did not see any improvement on mips and ppc, but could see the footprint
improvement on x86, arm & x86-64.

Also checked that the executables were not broken after the mklibs
optimization.
