[Qemu-devel] [PATCH v2 00/25] per-directory Makefile.objs snippets, limit vpath (ab)use

[Paolo Bonzini]

Here is v2 of the nested Makefile patches.  Thanks all for the enthusiasm!

The main change is that rules can now be put in the per-directory snippets.
This is done for op_helper.o already.

Paolo

v1->v2:
        do not call nested files "Makefile" (Andreas)
        do not create directories at configure time (Anthony)
        allow per-snippet rules, use it for op_helper.o (Blue Swirl)
        whitespace fixes (Blue Swirl)
        fix Xen (myself)
