autoconf 2.57 and DJGPP: Test for 'make -C' setting $(MAKE)

[Richard Dawe]

Hello.

The test to check whether 'make -C' sets $(MAKE) doesn't quite work if $(MAKE)
is an absolute DOS path like c:/djgpp/bin/make.exe. Below is a ChangeLog and
patch to cope with DOS paths in this test. We translate ':' in $(MAKE) to '_'.

Thanks, regards,
