Dan Nicholson a1de400e8d mklib: Extract archives into temporary directories 
When static libraries are created from other archives, objects are
extracted and then deleted when the static library is done. This can
race when there are multiple static libraries being created from the
same archives as with libmesa.a and libmesagallium.a.

Should fix this issue with parallel jobs:

make[5]: *** No rule to make target
> `../../../../../../src/mesa/libmesagallium.a', needed by
> `radeon_dri.so'. Stop
