Testing with what I think is the later commit 84264b99322
the all-linux-static build fails "make check":

[various other output from other parallel jobs snipped]

This is from the build whose configure rune is
'--cc=ccache gcc' '--enable-debug' '--static' '--disable-system'
'--disable-gnutls'

Also one of my random "just test linux-user" setups fails
because the build doesn't seem to have put the final binaries
in the right place:

make: Entering directory '/home/petmay01/linaro/linux-user-test-0.3'
./qemu-linux-user.sh
[qemu-i386]
/home/petmay01/linaro/qemu-for-merges/build/all-linux-static/i386-linux-user/qemu-i386
-L ./gnemul/qemu-i386 i386/ls -l dummyfile
./qemu-linux-user.sh: 54: ./qemu-linux-user.sh:
/home/petmay01/linaro/qemu-for-merges/build/all-linux-static/i386-linux-user/qemu-i386:
not found
Makefile:6: recipe for target 'test' failed
make: *** [test] Error 127
make: Leaving directory '/home/petmay01/linaro/linux-user-test-0.3'

I can live with the .o files moving around (though I would have
preferred it if they did not), but the final binaries should be
being built into the same places we always have. Otherwise we're
going to break a lot of "just run from the build tree" setups
and instructions.

Everything else seems to have passed.
