Hmm now the build fails :(

At the bottom of the log file I see..
<snip>

The only error I can see that isn't also marked ignored is..
:info:build checking for sched.h... yes
:info:build checking for unistd.h... (cached) yes
:info:build checking for thread model used by GCC... single
:info:build checking whether the target supports thread-local storage... configure: error: Link tests are not allowed after GCC_NO_EXECUTABLES.
:info:build checking fcntl.h usability... yes

:info:build make[1]: *** Waiting for unfinished jobs....
:info:build no
:info:build checking for objdir... .libs

Is there a way to prevent it using -j 4 in the build to make the problem clearer?

Thanks.
