[1/4] Probe catch syscall support
Commit Message
In 82075af2c14b1f8a54fa5796fb63f7ef23f98d9d (Implement 'catch syscall'
for gdbserver), only x86 is supported, but the test can still be run
on other linux targets, like aarch64 and ppc, with native-gdbserver.
This causes many new fails.
This patch removes the check on isnative and on target triplets.
Instead, we can insert catch point, and resume the program to see whether
catch syscall is supported or not.
gdb/testsuite:
2016-06-16 Yao Qi <yao.qi@linaro.org>
* gdb.base/catch-syscall.exp: Remove check on isnative and target
triplets. Start gdb, execute catch syscall, and continue. Check
gdb's output to determine catch syscall is supported.
