Subject: configure: use standard check for attribure alias
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=95d9eae42745d958d94445dbfb343dd1927ba9d6;p=mesa.git

configure: use standard check for attribure alias

Currently we have two macros - HAVE_ALIAS and GLX_ALIAS_UNSUPPORTED.
To make it even better former of which is explicitly cleared in some
cases while not in others.

Clear all that up by using a single macro properly set during configure.
