Be careful as this is controlled system wide, not per process. ;-)
And to be clear, I've not messed with this in a long long time so please try on a TEST system first!
sysctl is what you're looking for:
$ sysctl -a kern.corefile
kern.corefile: /cores/core.%P
>From bsd/kern/kern_proc.c in xnu-1504.7.4 (OSX 10.6.4)
/*
* proc_core_name(name, uid, pid)
* Expand the name described in corefilename, using name, uid, and pid.
* corefilename is a printf-like string, with three format specifiers:
* %N name of process ("name")
* %P process id (pid)
* %U user id (uid)
* For example, "%N.core" is the default; they can be disabled completely
* by using "/dev/null", or all core files can be stored in "/cores/%U/%N-%P".
* This is controlled by the sysctl variable kern.corefile (see above).

Enjoy!
