I noticed a buildbot failure where gdb crashed in info-os.exp, when
compiled with -D_GLIBCXX_DEBUG:
(gdb) info os procgroups
/usr/include/c++/7/bits/stl_algo.h:4834:
Error: comparison doesn't meet irreflexive requirements, assert(!(a < a)).
Objects involved in the operation:
iterator::value_type "< operator type" {
type = pid_pgid_entry;
}
The bug here is that pid_pgid_entry::operator< violates the C++
irreflexivity rule; that is, that an object cannot be less than
itself.
Tested locally by re-running info-os.exp.

* nat/linux-osdata.c (pid_pgid_entry::operator<): Fix
irreflexivity violation.
