Fixing problems at their source - in this
case fixing gdb - is of course the best solution.

For the w64 port of gdb, I needed a quick solution.
Usually it will take some time to ask the gdb maintainers,
find a solution, get distributions which include the solution
and use such distributions everywhere.

I don't think that the setup with pe-coff (when it is supported)
will be 100 % identical to the elf setup, so most probably we'll
need a test for ELF / not ELF anyway.

Therefore I suggest to apply my patch, even it is only an
intermediate solution for the next year.
