pass our compiler -fasynchronous-unwind-tables by default
This should make more platforms (in particular, ones with compilers
where -fomit-frame-pointer is on by default but table generation
isn't) support backtrace generation. Thanks to cypherpunks for this
one.
Fixes bug 11047; bugfix on 0.2.5.2-alpha.
