Todd Gamblin bb5d83890d cc: refactor flag adding so that it's not in reverse order ... - flags were prepended in reverse order to args, but this makes it hard to see what order they'll be in on the final command line. - add them in the order they'll appear to make cc easier to maintain. - simplify code for assembling the command line - fix separator used in SPACK_SYSTEM_DIRS test		2018-08-08 01:51:51 -07:00
