fixup fontconfig.rb (linux mint 17, gcc 4.9)

This applies the patches I mentioned in the first 3 posts of
issue #164

1) Add -lpng to the LDFLAGS
2) Add --disable-docs to the configuration flags

See compilation notes here:
http://www.linuxfromscratch.org/blfs/view/svn/general/fontconfig.html

It appears that --disable-docs only disables the compilation of
the docs from their sources, and the actual results are in fact
distributed with the tarball, so they can still be installed.

It's hard to see that explicitly adding -lpng as I did can lead
to anything bad.
fixup blockers for cairo.rb

I had two issues

(1) it explicitly relies on XQuartz. fix with `unless os.Mac?`
(2) the cairo test suite fails, this apparently is caused by
gcc 4.9, see here:

https://bugs.archlinux.org/task/40313

I fix it by adding an extra cflag to the make invocation as
described in the report.
