Re: [Crash-utility] RFC: crash extension module handling

I'm going to change the extensions/Makefile to the attached version, which will build any solo .c file with the traditional compile line. For special-case extensions that require a different build procedure, like sial.c, an accompanying sial.mk file should also exist in the extensions directory. And, many thanks to Jeff Moyer for whipping the Makefile into shape.
