+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.
