[m-rev.] for review: another MinGW portability fix

[Fergus Henderson]

Estimated hours taken: 1

Another change needed to port Mercury to work on MinGW <http://www.mingw.org>.

boehm_gc/Makefile:
	If using "if_not_there foo.o $(CC) ..." fails,
	then try "if_not_there foo.o `cygpath -w /bin/sh` -c $(CC) ...".
	This is needed when `if_not_there.c' is compiled with MinGW,
	and $(CC) is a shell script (mgnuc), since `if_not_there.c'
	uses exec() and the MinGW exec() of course doesn't handle
	Bourne shell scripts.
