Now that QEMU is always built out-of-tree, the rules to build
QEMU need not be in a file called "Makefile". Move them to
"Makefile.build" (which is symlinked to Makefile in the build
tree) and only leave the support for fake in-tree build in the
source directory Makefile. This support is enabled conditionally
if the marker file is found in the build/ directory, and therefore
configure does not have to create a makefile of its own anymore.

Hi Paolo,
This doesn't apply on master, likely because some changes got
merged this week-end with the latest PR of the trivial tree.
Also, please use my <groug@kaod.org> address for upstream work.
Cheers,
