[DTrace-devel] [PATCH v3 6/9] build: force regeneration of config.{h, mk} when configure options change

[Nick Alcock]

Now that we are actually rerunning configure tests only when needed, we need
to force regeneration of config.h more reliably (we can't depend on the
stamp file to do it for us, since that is now updated only when the
directory as a whole is deleted).  Just have the individual configure tests
delete the generated accumulated config files, forcing regeneration with the
new content produced by that rule.
