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.

Fixed:
* gcc 5 introduces a plugin libcc1.so, which is used by gdb, the target
gcc didn't build it in the past because gcc_cv_objdump is null, and
the error was:
gcc-5.2.0/libcc1/configure: line 14531: -T: command not found
This only happens for tar gcc as the code shows:
if test x$build = x$host; then
export_sym_check="objdump${exeext} -T"
elif test x$host = x$target; then
export_sym_check="$gcc_cv_objdump -T"
else
export_sym_check=
fi
* Install libcc1.so and libcc1plugin.so to
$(libexecdir)/gcc/$(target_noncanonical)/$(gcc_version) as lto-plugin did.
* Use sed command to fix bad RPATH iussue.
