[cairo] How to cross compile py2cairo

[suzuki toshiya]

Hi,

I guess your testing "import _cairo" does not work even under
the self hosting environment in GNU/Linux i386, even if
_cairo.so is correctly built.
I propose to proceed step-by-step manner;

1) build py2cairo for hosting GNU/Linux via waf (as INSTALL tells),
with a python whose version is same with the python running in your
ARM target.

2) install py2cairo via waf, and test what you want to do on ARM
target. Also it is important to check which files are required
to work.

3) build _cairo.so for hosting GNU/Linux by some method you want
to try (e.g. gcc -shared -o _cairo.so *.c ...), replace _cairo.so
in installed directory, and test what you want to do on ARM target.

4) build _cairo.so for target GNU/Linux by some method you want
to try, and copy the required files (checked in step 2) to the
target.
