This is weird, because uClibc doesn't build for me with O=, since
bee5745ccc20be6dbba243b1f8af0d5c522923e8 (Makefile: don't depend on the umask).

It seems that Arnout was not affected by this issue when reviewing/testing.
Also someone else reported this issue on IRC today.

My umask was 0002 and I had to set it to 0022 to workaround the issue.
