Subject: mesa: Fix build of ES overlay.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=a6ec153830ea25958f8cb5f5b5ae7a3433d61bbc;p=mesa.git

mesa: Fix build of ES overlay.

ES overlay is built with FEATURE_ES1 or FEATURE_ES2, and is built
without FEATURE_GL.  Fix the build by always building OpenGL ES sources,
but test for FEATURE_ES1 or FEATURE_ES2.  Also, define symbols that are
missing because FEATURE_GL is not defined.
