Subject: configure.ac: Add support for Android builds
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=27d713a004da1918d1c5699b077734eceb0ebd75;p=mesa.git

configure.ac: Add support for Android builds

Add support for EGL android platform.

Also, detect when --host finishes with -android. In that case, we
do not set _GNU_SOURCE, and define autoconf symbol HAVE_ANDROID, so
that Android-specific workarounds can be applied.
