* x11 = xlibsWrapper on non-Darwin systems, but is darwinX11AndOpenGL on
  Darwin systems, so pass in xlibsWrapper to the lesstif build instead

graphite2: enable build on Darwin

This builds on Darwin without any modifications, so it has been added to
the platforms array
re-enable au debian mirror
upgrade texlive-extra to 2013.20140215

The old version (2013.20131112) was no longer available on the debian
mirrors, hence building from source was impossible.
upgrade texlive-base, texlive-lang

Upgraded to 2013.20140215. The old version (2013.20131112) was no longer
available on the debian FTP server, so building from source was
impossible.
texLiveFull: fix build on Darwin

Added --with-system-icu=no, --with-system-harfbuzz=no (looks like the
omission of --with-system-icu was not sufficient to force the builder
not to look for system ICU libs).

Disable building bibtex-x: complains about missing ICU directory.

Disable building dvisvgm: a test fails (and I can't work out how to
prevent the tests from running just for this).

Disable building devnag: failing tests.
