    binutils: apply RPATH fixes from our libtool patches
    
    We don't autoreconf/libtoolize binutils as it has very strict requirements, so
    extend our patching of the stock libtool to include two fixes to RPATH
    behaviour, as part of the solution to ensure that native binaries don't have
    RPATHs pointing at the host system's /usr/lib.
    
    This generally doesn't cause a problem but it can cause some binaries (such as
    ar) to abort on startup:
    
    ./x86_64-pokysdk-linux-ar: relocation error: /usr/lib/libc.so.6: symbol
    _dl_starting_up, version GLIBC_PRIVATE not defined in file ld-linux.so.2 with
    link time reference
    
    The situation here is that ar is built and as it links to the host libc/loader
    has an RPATH for /usr/lib.  If tmp is wiped and then binutils is installed from
    sstate relocation occurs and the loader changed to the sysroot, but there
    remains a RPATH for /usr/lib.  This means that the sysroot loader is used with
    the host libc, which can be incompatible.  By telling libtool that the host
    library paths are in the default search path, and ensuring that all default
    search paths are not added as RPATHs by libtool, the result is a binary that
    links to what it should be linking to and nothing else.

+Apply these patches from our libtool patches as not only are redundant RPATHs a
+waste of space but they can cause incorrect linking when native packages are
+restored from sstate.
+
+fix-rpath.patch:
+We don't want to add RPATHS which match default linker
+search paths, they're a waste of space. This patch
+filters libtools list and removes the ones we don't need.
+
+norm-rpath.patch:
+Libtool may be passed link paths of the form "/usr/lib/../lib", which
+fool its detection code into thinking it should be included as an
+RPATH in the generated binary.  Normalize before comparision.
