[Mesa-dev] [PATCH 03/12] util: automake: rework the format_srgb.c rule

[Emil Velikov]

A hardful of changes/cleanups paving the way to bmake support:
 - Don't bother with a $(srcdir) to the prereq list.
 - No space after the AM_V_GEN variable.
 - Using $< in a non-suffix rule is a GNU make idiom.
 - Use $(@D) over $(dir $@). The latter makes bmake unhappy.

XXX: Many places from now on use/set the following two variables.
 - Should we fold them somewhere - makefile/configure.ac ?
 - Can we reuse them (or the whole rule with android, via
makefile.sources - needs scons fix, otherwise) ?
 - Can/should we unconditionally call `mkdir -p .' and fold the two
variables ?

   PYTHON_GEN and MKDIR_GEN
