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. This patch adds tweaks to the relocation script to handle the new section too.
