Comment:
Would like some feedback on how I've implemented this.

At present, I've added libbacktrace.a to libgcc-devel, and ghdl uses that for the llvm backend (it just copies it). It irks me a bit that it copies libbacktrace, and I'm also not happy with the way I've got the template detecting where to find libbacktrace.a

A few possible solutions:
1) Fix detection of /usr/lib/gcc/<target>/<minver> for cross builds, maybe update the libbacktrace copy to a symlink while we're at it.
2) Use [ianlancetaylor/libbacktrace](/ianlancetaylor/libbacktrace) instead (they unfortunately don't seem to do any versioning at all).
3) Download gcc source and build libbacktrace from that (gcc source will eventually be needed anyway for building ghdl-gcc)

Any thoughts?
