This will never work; make files are not executable. You have to
say "make <target_in_makefile>".

This is because all of the kernel makefiles assume that they are
being invoked via rules in the top level makefile, usually
/usr/src/linux/Makefile, which sets up a bunch of stuff that
the subdirectory make files need. You will need to
"cd /usr/src/linux ; make modules ; make modules_install"
to rebuild vfat.o, assuming you've configured VFAT support as a
module. Of course, only the things that actually need to
be rebuilt will be.

There may be a way to build stuff in subdirectories independently,
but I've never found out what it is.
