gdb: testsuite: use gdb_attach to fix attach-pie-noexec.exp
If /proc/sys/kernel/yama/ptrace_scope is 1, when execute the following
command without superuser:
make check-gdb TESTS="gdb.base/attach-pie-noexec.exp"
we can see the following messages in gdb/testsuite/gdb.log:
(gdb) attach 6500
Attaching to process 6500
ptrace: Operation not permitted.
(gdb) PASS: gdb.base/attach-pie-noexec.exp: attach
It is obviously wrong, the expected result should be UNSUPPORTED in such
a case.
With this patch, we can see "Operation not permitted" in the log info,
and then we can do the following processes to test:
(1) set ptrace_scope as 0
$ echo 0 | sudo tee /proc/sys/kernel/yama/ptrace_scope
$ make check-gdb TESTS="gdb.base/attach-pie-noexec.exp"
(2) use sudo
$ sudo make check-gdb TESTS="gdb.base/attach-pie-noexec.exp"
