Exposes cairos --disable-some-floating-point configure option

Cairo has a configure option to disable some code paths which make heavy use of
floating point math. On systems without hardware floating point, this can
improve performance. This patch exposes that option in the buildroot
configuration.

I don't have any problems with the option as such, but right now this option
doesn't do anything in cairo, so adding it seems pretty pointless:

grep -rls DISABLE_SOME_FLOATING_POINT cairo-1.8.10
cairo-1.8.10/configure
cairo-1.8.10/config.h.in
cairo-1.8.10/configure.ac

Hmm, that's a very good point! I guess my impression that it had made any
difference was a delusion... It does however seem to be used in current cairo
from git, I haven't checked if it's in any of the newer releases. Probably
worth holding off on this until cairo is updated to some version that uses it.

Ok, therefore closing the bug. Don't hesitate to reopen when/if a later version
of Cairo really support such an option. Thanks!
