jocke@1700: Description:
jocke@1700: 
jocke@1700: This patch is needed in situations where build system is running same version of
jocke@1700: binutils that is intended to be built  cross-native ( build != host = target)
jocke@1700:  and has shared libraries enabled. binutils/binutils
jocke@1700: Makefile has some tools which are built to run on build system. Toplevel makefile
jocke@1700: for binutils passes HOST_EXPORTS to sub-makefiles which also include RPATH_ENVVARS
jocke@1700: containing LD_LIBRARY_PATH which is modified so that it also includes host libraries
jocke@1700: like opcodes and libbfd which are just built for the host system. 
jocke@1700: 
jocke@1700: Now the problem is that same LD_LIBRARY_PATH value gets set in environment even
jocke@1700: for the tools that are being built for build system using CC_FOR_BUILD and the tools
jocke@1700: like as,ld it invokes from build machine get the LD_LIBRARY_PATH set to search
jocke@1700: the newly build host libraries like opcodes and bfd and if host is like a big endian
jocke@1700: system say (mips-linux) the build system linker and assembler do not run because
jocke@1700: ld.so tries to load these shared libraries instead of the ones from /usr/lib for 
jocke@1700: the build tools. 
jocke@1700: 
jocke@1700: This patch fixes the issue by clearing LD_LIBRARY_PATH for BUILD tools
jocke@1700: 
jocke@1700: This patch would be needed on other versions of binutils. I just cared about 2.20
jocke@1700: May be upstream is also interested in such a patch.
