Jongsung Kim - May 3, 2013, 9:31 a.m.
Building cross-tool based on gcc-4.8 fails while "Installing
pass-2 core C compiler", because building libgcc.mvars needs
libbacktrace.a that doesn't build. This patch inserts
a few lines configuring, and making libbacktrace into
to build gcc-4.8-based cross-tools successfully.
