Unfortunately, including defs.make in make/solaris/makefiles/vm.make
isn't the "right" way to get a top-level variable down into the
HotSpot build system. I cannot remember what breaks when you do that,
but it doesn't work right in all the ways that we build HotSpot.

For the HotSpot build system, you'll want to:

- update make/solaris/Makefile and add HS_ALT_MAKE to
   the BUILDTREE_VARS list:


- update make/solaris/makefiles/buildtree.make and add
   HS_ALT_MAKE to the rule that creates flags.make:

           [ -n "$(HS_ALT_MAKE)" ] && \
             echo && echo "HS_ALT_MAKE = $(HS_ALT_MAKE)"; \

The way I usually find all the right spots is I look for
where ZIPEXE is added to the above files and follow those
