Description:
------------
The buildsystem of php 5.4 somehow adds -DTHREAD=1 to the libtool commandline which causes the compile to fail at pthreads_thread.h:83

/usr/local/src/php-5.4.7/ext/pthreads/pthreads_thread.h:87: error: expected ')' before 'first'

since the definition of THREAD is not used anywhere in the code it can just be removed to work around that problem.
