1Being able to build a nativesdk gcc is useful, particularly in cases
2where the host compiler may be of an incompatible version (or a 32
3bit compiler is needed).
4
5Sadly, building nativesdk-gcc is not straight forward. We install
6nativesdk-gcc into a relocatable location and this means that its
7library locations can change. "Normal" sysroot support doesn't help
8in this case since the values of paths like "libdir" change, not just
9base root directory of the system.
10
11In order to handle this we do two things:
12
13a) Add %r into spec file markup which can be used for injected paths
14 such as SYSTEMLIBS_DIR (see gcc_multilib_setup()).
15b) Add other paths which need relocation into a .gccrelocprefix section
16 which the relocation code will notice and adjust automatically.
