Update: I somewhat successfully cross-compiled cairo.

See http://freeciv.org/~jdorje/crosscompile/cross-compiling.html#cairo 
for a full report (instructions for cross-compiling are at the top of 
that file).  I found three buglets (which I reported in separate mails); 
the attached patch contains all three fixes.

I ran into problems however when compiling test/read-png.c.  I don't 
have libpng installed so the PNG backend wasn't built.  However the 
read-png file doesn't seem to know this and tries to build itself 
anyway.  I'd try to fix this, but since I heard the PNG backend was 
going away, the check for it will probably change after that happens.
