gdb/testsuite: use "set sysroot" in gdb.multi/multi-target.exp.tcl
The multi-target tests involve some inferiors using remote targets. By
default, GDB uses target: as the sysroot, which makes it read loaded
libraries and their debug info through GDBserver. This makes the tests
run slower than necessary.
Pass `-ex "set sysroot"` when launching GDB in these tests, so that GDB
always reads from its local file system.
On a system where I don't have debug info for libc, that reduces run
time for
$ make check TESTS="gdb.multi/multi-target-*.exp"
from 1:15 to 0:45.
On this other system where debug info is installed though, it reduces it
from 13:00 to 1:45.
gdb/testsuite/ChangeLog:
* gdb.multi/multi-target.exp.tcl (setup): Add "set sysroot" to
GDBFLAGS.
