When the internal PCRE library of PHP is used, it tries to use a JIT
engine, which is only available on some architectures.
However, the mechanism used to disable JIT has changed in recent PHP
versions, and it now has a proper --without-pcre-jit option. Switch
over to that to properly disable JIT on unsupported platforms.
It has been tested to fix the build of PHP on ARC and Microblaze.
