+Subject: [PATCH] handle sysroot support for nativesdk-gcc
+
+Being able to build a nativesdk gcc is useful, particularly in cases
+where the host compiler may be of an incompatible version (or a 32
+bit compiler is needed).
+
+Sadly, building nativesdk-gcc is not straight forward. We install
+nativesdk-gcc into a relocatable location and this means that its
+library locations can change. "Normal" sysroot support doesn't help
+in this case since the values of paths like "libdir" change, not just
+base root directory of the system.
+
+In order to handle this we do two things:
+
+a) Add %r into spec file markup which can be used for injected paths
+ such as SYSTEMLIBS_DIR (see gcc_multilib_setup()).
+b) Add other paths which need relocation into a .gccrelocprefix section
+ which the relocation code will notice and adjust automatically.
+
+Upstream-Status: Inappropriate
+RP 2015/7/28
+
+Extend the gccrelocprefix support to musl config too, this ensures
+that gcc will get right bits in SDK installations
+
+Signed-off-by: Khem Raj <raj.khem@gmail.com>
+
+Added PREFIXVAR and EXEC_PREFIXVAR to support runtime relocation. Without
+these as part of the gccrelocprefix the system can't do runtime relocation
+if the executable is moved. (These paths were missed in the original
+implementation.)
