Moved mig out of gnumach into standalone distribution with
vanilla autoconf/automake build arrangement.
* configure.in, Makefile.am: New files.
* mig.in (prefix, exec_prefix, libexecdir): New vars set by configure.
(migcom): Find migcom in ${libexecdir}, and use @MIGCOM@ for its name.
(cpp): Use @TARGET_CC@ -E instead of @CPP@.
