cover 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.

Pull URL: git://git.pokylinux.org/poky-contrib.git
Branch: nitin/mklibs
Browse: http://git.pokylinux.org/cgit.cgi/poky-contrib/log/?h=nitin/mklibs

Thanks,

PATCH 2/4 elfutils: add a missing depedancy

In reply to Nitin A Kamble

From: Nitin A Kamble <[email protected]>

while implementing the mklibs optimization, found out that an executable from elfutils package, viz eu-findtextrel is dynamically linked to libbz2.so library. But the poky-image-minimal did not have that library.
adding the depedency to the bzip2 to get that library for eu-fundtextrel
executable.

There should be a package name here, e.g. RDEPENDS_${PN}.

Also, why is the shlibs code not picking up the dependency automatically? Is it dlopen'd?
