What package is it that has the conflicting utils.h file?  Any chance to get

but none of them have the path in -I.

It's Xen: when building QEMU as part of the Xen build process,
tools/Makefile uses --extra-cflags to add the local Xen directories to
the QEMU include path. However one of the Xen header files is named
utils.h, conflicting with utils.h from disas/libvixl.
It seems to be that --extra-cflags should come after the QEMU include

I think the bug is in Xen then.  I have an oldish checkout and I see:

$ find . -name utils.h

Could you move more headers to tools/include/ and avoid polluting QEMU_CFLAGS?

That said, for this particular case not using foo.o-cflags can be a stopgap solution too.
