Subject: configure.ac: Don't look for pthreads in Android platform
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=e23608db1cad3d3b86b5350255db4d47a0081d2e;p=mesa.git

configure.ac: Don't look for pthreads in Android platform

In Android, the pthreads libs are in bionic.  When building
Mesa for Android with the autotools workflow, we shouldn't
set -lpthread or -pthread.

[Emil Velikov]
Other platforms could use a similar fix, although that is left as
separate exercise.
