[PATCH] gdb.base/siginfo-thread.exp: Increase timeout for 'gcore' command

[Weimin Pan <weimin.pan@oracle.com>]

The following failed lines from running test case siginfo-thread:

FAIL: gdb.base/siginfo-thread.exp: save a core file (timeout)
FAIL: gdb.base/siginfo-thread.exp: extract si_addr
FAIL: gdb.base/siginfo-thread.exp: p ssi_addr

indicate the testsuite timed out when gdb was instructed to write the
core file. The patch below fixes the problem by simply increasing the
timeout by a factor of 2 to give gdb more time to generate core files.

Tested in sparc64-linux-gnu. No regressions.

        * gdb.base/siginfo-thread.exp: Increase timeout by a factor of 2
        for the 'gcore command.
