Description:
------------
When cross-compiling PHP for a different architecture, configure fails if you 
specify the --enable-fpm option:

==
checking for ptrace... yes
checking whether ptrace works... configure: error: in 
`/hdd/max/dev/raspberry/buildroot-berryserver/output/build/php-5.4.0':
configure: error: cannot run test program while cross compiling
See `config.log' for more details.
==

Obviously it is impossible to execute a test program when the system you are 
compiling on is not the target system.

Attached a patch that skips running the test programs when cross-compiling.

Had to dive a littl deeper because of cross-compileing php5.6.40 resulted, even ,with the patch, in a binary with unsupoorted extensions. Found that acincludes.m4-PHP_CHECK_FUNC_LIB cant compile its test in the cross-compile environment an so opts out with found=no reverting any other choice made before.
