[m-rev.] for review: Remove Cygwin hacks in boehm_gc/Makefile.direct

[Peter Wang]

We had these kind of lines:

    -./if_not_there mach_dep.o `cygpath -w /bin/sh` $(CC) ...
    -./if_not_there mach_dep.o /bin/sh $(CC) ...

They would have been necessary because $(CC) actually points to mgnuc,
a shell script, which the if_not_there.c program might not be able to
start with execvp().

Now that we have replaced if_not_there.c with a shell script, there
should be no need to refer to invoke /bin/sh explicitly.

Note that those lines were incorrectly merged into Boehm GC upstream.

boehm_gc/Makefile.direct:
	As above.
