Opps, when I tested, I *did* in fact use --disable-tools - just my email
here was wrong.

Ahh, this is useful.

You have your build directory *outside* the QEMU source tree,
eg $GIT/../build, whereas I had been testing with $GIT/build
and an non-VPATH build.

I can in fact reproduce if building completely outside the GIT tree
like you show.

I'll look at producing a fix shortly...

Daniel
