gdb build on Linux is missing bin/gdbserver and man/man1/gdbserver.1 from
PLIST.

gdb-5.3/gdb/README says:
   The directory gdb/gdbserver/ contains `gdbserver', a program that
   allows remote debugging for Unix applications.  gdbserver is only
   supported for some native configurations, including Sun 3, Sun 4, and
   Linux.

gdb-5.3/gdb/configure.tgt checks a lot of target_cpu's and then sets
build_gdbserver=yes.

The fix for this package is to have a PLIST.Linux (or a PLIST.command and
PLIST.Linux) (And also for s390 and s390x -- PLIST.SunOS, I guess.)

Should I send-pr this? Or fix it?
