Subject: [PATCH] sync with OE libtool changes

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.

Upstream-Status: Inappropriate
