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.

As far as I know we have not tried that. Doesn't this change some of the
processing though for systems that use unwind as the only way to generate proper
back traces?

we already disable it for gcc-runtime and libgcc recipes where it would matter too.

For what it's worth, --disable-libunwind-exceptions doesn't seem to prevent
the failure.
In file included from /home/seebs/tct/t00/bitbake_build/tmp/work-shared/gcc-4.8.
0-r0/gcc-4.8.0/libstdc++-v3/libsupc++/eh_arm.cc:26:0:
/home/seebs/tct/t00/bitbake_build/tmp/work-shared/gcc-4.8.0-r0/gcc-4.8.0/libstdc
++-v3/libsupc++/unwind-cxx.h:92:3: error: '_Unwind_Ptr' does not name a type
[... and many, many, more]
This appears to be identical to what we get without
--disable-libunwind-exceptions. It may be that that isn't fully implemented
for libsupc++.

Listen, get this. Nobody with a good compiler needs to be justified.
