Continuing from the failure described in PR d/87865 with the workaround
mentioned
there,libphobos fails to configure:

configure: error: can't compile D sources!

config.log shows

When I run the compiler under truss -f, I find that it only looks in its
 working directory for some reason:

4398:   read(4, " m o d u l e   m o d ;\n".., 50)       = 50
4398:   close(4)                                        = 0
4398:   stat64("object.di", 0xFFBFE980)                 Err#2 ENOENT
4398:   stat64("object.d", 0xFFBFE980)                  Err#2 ENOENT
4398:   stat64("object", 0xFFBFE980)                    Err#2 ENOENT
4398:   open64("object.d", O_RDONLY)                    Err#2 ENOENT

I haven't yet dug further or compared with what happens on Solaris 11 where
this works fine.
