note, that this seems to be only happening on master:
if I checkout another tag (git checkout v2.067.1-b1 or any other I've tried) it builds fine.
So it must be a very recent regression
It's not a regression. Shortly after 2.067 was released, dmd got the new requirement of a host D compiler to build. You can explicitly set which compiler to use by setting the HOST_DC environment variable. If you also want to build ddmd, then 2.067 is recommended as it is known to work on all autotester platforms. In posix.mak HOST_DC defaults to 'dmd' which will correctly pick up a dmd installation in path, as long as you don't have a sc.ini file in the dmd src dir.
