OK, now I think I know what's going on. mklib will extract all the
object files from dependent .a archives. libmesa.a and
libmesagallium.a will both extract sl_pp_context.o to the current
directory, repack them into their own archives, and then delete the
extracted objects. Since libmesa.a and libmesagallium.a are building
in parallel, there is a race where they're both extracting then
deleting the objects. Something like this:
libmesa.a: extract objects
libmesagallium.a: extract same objects
libmesa.a: insert objects
libmesa.a: remove objects
libmesagallium.a: insert now removed objects
The failure is on the last step because libmesa.a has just removed
sl_pp_context.o. Here's the hacky fix (you'll have to edit manually
since gmail will break formatting):
diff --git a/src/mesa/Makefile b/src/mesa/Makefile
index f845d93..4425000 100644
--- a/src/mesa/Makefile

The more correct fix is to have mklib extract in a temporary
directory. Something like this totally untested attached patch.
