The backtrace is usually better for QEMU with TCG interpreter. Run
configure --enable-tcg-interpreter
The resulting binaries are much slower, but no longer create
code on the fly, so you get normal backtraces.
I also had to remove -fstack-protector-all (in file configure) to
get good backtraces for w32/w64.
