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 Signed-off-by: Joachim Nilsson <jocke@vmlinux.org>

Description:
This patch is needed in situations where build system is running same version of
binutils that is intended to be built cross-native ( build != host = target)
and has shared libraries enabled. binutils/binutils
Makefile has some tools which are built to run on build system. Toplevel makefile
for binutils passes HOST_EXPORTS to sub-makefiles which also include RPATH_ENVVARS
containing LD_LIBRARY_PATH which is modified so that it also includes host libraries
like opcodes and libbfd which are just built for the host system.
Now the problem is that same LD_LIBRARY_PATH value gets set in environment even
for the tools that are being built for build system using CC_FOR_BUILD and the tools
like as,ld it invokes from build machine get the LD_LIBRARY_PATH set to search
the newly build host libraries like opcodes and bfd and if host is like a big endian
system say (mips-linux) the build system linker and assembler do not run because
ld.so tries to load these shared libraries instead of the ones from /usr/lib for
the build tools.
This patch fixes the issue by clearing LD_LIBRARY_PATH for BUILD tools
This patch would be needed on other versions of binutils. I just cared about 2.20
May be upstream is also interested in such a patch.
