Module build broken on master.

Hi there,

I just did a clean build of the master branch (pulled 10-30 minutes
ago), and it seems that a module build is broken.

When I do,

cd sal
make

instead of just building the sal module, I'll get

$ cd sal
$ make
/home/kyoshida/libo/feature/working-branch-1/sal//../solenv/gbuild/partial_build.mk:10:
/home/kyoshida/libo/feature/working-branch-1/sal/../../config_host.mk:
No such file or directory
/home/kyoshida/libo/feature/working-branch-1/sal//../solenv/gbuild/partial_build.mk:14:
/gbuild/gbuild.mk: No such file or directory

this was working fine with the build as of last night.

Any ideas?
