Drop non-USES make variables for PHP

[brnrd]

Summary

Mk/Uses/php.mk was introduced in June 2016 and we still have the
compat variables available for users. This is unneccessary clutter
in the ports framework.

Depends on D15012

All instances of WANT_PHP_*, USE_PHPIZE, USE_PHPEXT, USE_ZENDEXT and USE_PHP_BUILD have been removed from ports with commits earlier today. rP466789 rP466790 rP466792 rP466793 rP466794 rP466796 rP466797 rP466799

Some more remnants of WANT_PHP_*

Looks fine to me! :)

@mat or @antoine OK to commit this one?

There are also USE_PHP*_ALT and WANT_PHP*_ALT variables near the end of bsd.sanity.mk, those should be removed too.

But I wonder if the cleanup is too soon, given that there are still warnings for e.g. USE_RC_SUBR

No need for _ALT when knob is UNSUPPORTED

Updated the diff.. _ALT doesn't make sense if the knob is UNSUPPORTED

Not sure what is meant with this... Can you elaborate?

Thanks!

It could be that third-party software is still using those variables. Perhaps add a note to CHANGES ?
