Break out the rules which generate crunchgen'ed binaries into a separate
.mk file so they can be reused. Introduce a new option, CRUNCH_BUILDTOOLS, which lists the binaries that require tools built in the local architecture. sh and csh both require this. It was previously hardcoded in rescue/rescue/Makefile . Introduce a new option, CRUNCH_SHLIBS, which lists the shared libraries to link against. These override the static libraries listed in CRUNCH_LIBS. Some build environments may wish to use a handful of shared libraries (eg libc.so) so other small, dynamic binaries can be run in the environment. Remove the now-shared code from rescue/rescue/Makefile and introduce the CRUNCH_BUILDTOOLS option for the above shells.
