configure, gbuild: remove Cygwin paths from make environment

All environment variables contain native Win32 paths.

This allows building with Win32 make and Cygwin sh.exe,
but Cygwin make cannot build any more with the Win32 entries in PATH.

Requires adding "bash" detection to configure since /usr/bin/env
can't be invoked by Win32 make and it's possible to install cygwin
somewhere else than C:/cygwin.
