[Xen-devel] [PATCH] tools/Makefile: unset MAKELEVEL before building QEMU

[Anthony PERARD <anthony.perard@xxxxxxxxxx>]

Since QEMU commits aef45d51d1204f3335fb99de6658e0c5612c2b67
"build: automatically handle GIT submodule checkout for dtc"
the QEMU makefiles rely on the variable MAKELEVEL to make a decision on
whether to update some git submodules or not. Since we call QEMU build
from within the Xen one, MAKELEVEL would already be greater than 0 and
the git submodules would not be updated and QEMU would fail to build.

Fix this by removing MAKELEVEL from the environment before trying to
build QEMU.
