In openembedded(.org), we have cairo graphics working perfectly on ARM
and PowerPC, and the revisions we tested are listed here:

This sounds like a toolchain problem, most probably either endianess
related, or more probably (soft?) floating point related.

I would strongly suggest to run some floating point tests on your target first.

Personally, I mostly use a ARM/XScale (arm5teb) target, and PowerPC
(e300) target in combo with cairo, no problems so far.
