1.0.41.52: more make.sh tweakery

 * Empty string as the value for an option is treated as if the option
   wasn't provided at all, which makes scripting builds easier.

 * Temporary support for legacy-style xc host specifications for the
   benefit of clbuild &co. Add a noisy message to the end of the build
   so people will hopefully notice.
