I would like to point out that this is only about compiling with debug
symbols, not about changing the optimization level. GCC and clang support
this although apparently some compilers don't. The executable code should
be identical.

This is a great point. There should probably be an easy way to get all of
the required symbols because downloading one by one will be a pain. This
should be fairly easy to do with a python gdb extension.

Definitely inspired.
