[Mesa-dev] [PATCH] android: fix Android.mk bug in mesa/drivers/dri/common

[groleo at gmail.com]

From: Adrian Marius Negreanu <adrian.m.negreanu at intel.com>

target-specific variables are undefined when used as pre-requisites.
instead, use secondary-expansion.

I noticed this when building the patch:
     i965: Add a driconf option to disable flush throttling
