[Mesa-dev] [PATCH 0/2] share source lists between build systems

[Chia-I Wu]

This patch series enables Makefile, SConscript, and Android.mk to
share their source lists.  The idea is to first factor out source
lists from Makefile to Makefile.sources.  Then by adding the ability
to parse Makefile.sources to SConscript, all three build systems can
share it.

In this series, only gallium/auxiliary is updated, mainly to serve as
an example.  There is no plan to update _every_ directory at the
moment.  Directories will be updated as needed.

Comparing to the RFC version of the series,

 - sources.mak is renamed to Makefile.sources
 - the SCons method to parse Makefile.sources is now called
   ParseSourceList and the input file name must be specified
 - better error reporting for the parser
