Handle some compiler versions containing a dash

Browse source 
The version reported by e.g. x86_64-w64-mingw32-gcc on Debian bullseye
looks like:
  gcc version 10-win32 20210110 (GCC)

This ends up with detect-compiler failing with:
  ./detect-compiler: 30: test: Illegal number: 10-win32

This change removes the two known suffixes known to exist in GCC versions
in Debian: -win32 and -posix.
