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.

Add build directory to include directories by -I${B}/include which will
be searched before standard system include directories.
Both libunwind and gcc supply unwind.h, once gcc use libunwind's unwind.h,
the compiling will fail.
This patch is generally not applicable to the upstream as they do not
use libunwind.
