I had the same problem with version 5.2.5 when trying to cross compile for the PowerPC. The comments in these two bug reports gave me a solution:

http://bugs.php.net/bug.php?id=41951
- I changed the values of the variables mentioned to 4
http://bugs.php.net/bug.php?id=45148
- I forced ac_cv_c_bigendian_php=yes as suggested

And like I said in the other reports: cross-compiling is not supported out-of-box.
