binutils/binultils: import binutils-2.20 patches from OE

This is a set of patches for binutils-2.20 that have been "ported", or rather
shamelessly stolen, from the OpenEmbedded project:

http://cgit.openembedded.org/cgit.cgi/openembedded/tree/recipes/binutils/binutils-2.20

Tried and tested on Arm (big-endian Xscale, and little-endian i.MX27) with GCC 4.4.2
