[PATCH 0/3] Remove recursive configure for Cygwin

[Jon Turney]

A couple more Makefile/configure cleanups, and remove recursive configure
for Cygwin.

For ease of reviewing, this patch series doesn't contain changes to
generated files which would be made by an autoreconf.

Jon Turney (3):
  Remove intro2man.stamp on clean
  Drop AC_SUBST(build_exeext)
  Remove recursive configure for cygwin
