You can skip build of and import hotspot with
--with-import-hotspot=/path/to/hotspot which can either point to a full
jdk or the export dir from a hotspot build directory.
MSYS has limited support, but is not faster than cygwin in my
experience. Last I tried, MSYS required a JOBS=1 build to not crash.
