I've now added a patch for configure.ac and Makefile.am (as well as re-genned configure and Makefile.in) so that the gcc build system is doing the heavy lifting. These changes mostly came from looking at a diff between gcc/libbacktrace and ianlancetaylor/libbacktrace.

libbacktrace from gcc now split into its own subpackage, and I've made it a separate commit as requested in one of your review comments.
