Fix build with gcc 4.9
cairo fails to build with gcc 4.9 due to a bad interaction of cairo
modules with the LTO mechanism. The suggested workaround is to pass
-ffat-lto-objects. See
https://bugs.freedesktop.org/show_bug.cgi?id=77060 for the upstream
bug report, and
https://bugs.archlinux.org/task/40313?project=1&openedfrom=-1+week for
the ArchLinux bug report.
This patch passes -ffat-lto-objects when gcc understands this option,
in order to provide compatibility with gcc versions older than 4.8,
which did not provide this option, but are anyway unaffected by the
issue.
