From 397884efce0bb7c3f1ff5e1da212e874c7eaf14b Mon Sep 17 00:00:00 2001

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
