[PATCH] Skip bigcore.exp on AIX

[Aditya Vidyadhar Kamath <akamath996@gmail.com>]

From: Aditya Vidyadhar Kamath <aditya.kamath1@ibm.com>

AIX does not support sparse core files, so bigcore.exp, which
allocates up to 16GB and then dumps core, is too slow and large there
and fails.  Add AIX to the list of targets without sparse corefile
support, so that the test is reported as untested.
