Description:
        Rediffed for 2.19.1 by Jim Gifford
        Rediffed for 2.10 by Joe Ciccone

        Updated patch, use this for all binutils 2.15 series instead of the
        binutils-2.15.90.0.1-genscripts-multilib.patch

        If --with-libpath= was specified during configure (or LIB_PATH was
        supplied during make) we want to have these libraries added to the
        linker scripts search paths, and in the case of multi-lib have them
        processed to provide both lib and lib64 search paths.
        This patch produces this behaviour when building a cross-binutils.

        Also to fix an annoyance we remove whatever was specified (if anything)
        by --libdir= from the linker script search path. This is so when cross-
        compiling a 64bit target-native biarch toolchain we can specify the
        installation directory for binutils produced libraries to be */lib64
        without having this directory added to the 32bit emulation search path.

        By rights we should really check if ${libdir} matches a search path in
        any of the supported emulations for this target (as opposed to only the
        one genscripts.sh is currently processing) and if so ignore ${libpath}.

        This patch differs from the preceding genscripts-multilib patch as now
        USE_LIBPATH will always be set if LIB_PATH is non empty
