[Qemu-devel] [PATCH v2] Force object directory use

[Blue Swirl <blauwirbel@gmail.com>]

[-- Attachment #1: Type: text/plain, Size: 29950 bytes --]

If the user attempts to run 'configure' in the source tree,
create an object directory and configure that instead.

Rename topmost Makefile to Makefile.top. Add a new Makefile, which
is only used when user attempts to run 'make' in the source tree.
