experimental patch for graphics/gd

Life cycle of the gdFontCacheMutex related to fontCache seems to be wrong and
fontCache may be used when it is NULL.
This problem seems to be resolved in the bundled version of PHP.
It seems to me that a bundled version should be used for php, but I guess a
combination of mod_php (e.g. mod_php81+php81-gd) and mod_perl (e.g.
ap24-mod_perl2+p5-GD), etc. would cause conflicts in the symbol table. but I
don't know :)
So I have prepared a patch that I think will make this equivalent to the
bundled version of php.
The option is THREADS for now, but I think the meaning is different :)
