[Qemu-devel] [PATCH] Makefile: disable parallel build with dtc

[Michael S. Tsirkin]

Sometimes I get this error when building with -j 4:
ar: two different operation options specified
make[1]: *** [libfdt/libfdt.a] Error 1
make: *** [subdir-dtc] Error 2

dtc make does not seem to support parallel make.
Force non-parallel build to fix this.
