All current dev-lang/php ebuilds still point to the now deprecated make.conf path /etc/make.conf in their elog output. They all should be updated to refer to /etc/portage/make.conf instead. See also bug#452176.
Fixed in cvs.
dev-lang/php-5.5.3-r1 still refers to /etc/make.conf. It seems this bug is not really fixed yet.
Please also see bug 472012.

Please re-open. This is still unresolved in: dev-lang/php-5.6.22 dev-lang/php-7.0.7-r1 I've attached patches to actually resolve this bug.
We're doing a few version bumps for security fixes and I'm going to fix this by... being more vague. Pointing to /etc/make.conf is definitely wrong, but pointing to /etc/portage/make.conf isn't optimal either. Even with portage, it will often be preferable to set them in package.use (see bug #471776). But we support other package managers that won't have either make.conf or package.use. For the most generality, I'm not going to say anything helpful at all =) To build extensions for this version of PHP, you will need to add php7-0 to your PHP_TARGETS USE_EXPAND variable.
