What does ghdl use libbacktrace for, specifically?

I think using GCC's, since it's already there, is "reasonable". But it should be its own subpackage, the ugliness should be opt-in.

> Download gcc source and build libbacktrace from that (gcc source will eventually be needed anyway for building ghdl-gcc)

What does it need GCC for?
