Subject: Add ability to specify "compiler mode" options as part of
 config.{c,cxx}

Such options are (normally) not overridden by buildfiles and are passed
last (after cc.coptions and {c,cxx}.coptions) in the resulting command
lines. They are also cross-hinted between config.c and config.cxx. For
example:

$ b config.cxx="g++ -m64"
