Another option (if running on a newer kernel) is to use some of the formatting
strings in /proc/sys/kernel/core_pattern

for example: 
$ sysctl -w kernel.core_pattern=/tmp/%e.%p

will result in core files places in tmp, with the executable name, and an
extension of the PID.

Other format specifiers are listed in Documentation/sysctl/kernel.txt [1]
