dpkg-buildpackage -S fails too, and it can be reduced to this:

€ fakeroot-hurd
# cat test.c
#include <sys/stat.h>
int main(void) {
        mkdir("/tmp/foo", 0700);
        chmod ("/tmp/foo", 0700);
        return 0;
}
# make test
# ./test
# ls -ld /tmp/foo

Indeed, the returned mode is now 700, not 40700.  The attached patch,
now commited, fixed it.
