* gdb.base/corefile.exp: Move the core finding block out and call it as core_find, new variable $corefile, replace corefile by $corefile and [file tail $corefile] for usage vs. test names resp. * lib/gdb.exp (core_find): Move it as a new function here. New parameter binfile and deletefiles. New variable $destcore. Pre-delete $destcore. Return "" on error.
