This enables proper support for multiple inferiors and ptrace(2)
assisted management of the inferior processes and their threads.
(gdb) info inferior
Num Description Connection Executable
* 1 process 14952 1 (native) /usr/bin/dig
2 <null> 1 (native)
3 process 25684 1 (native) /bin/ls
4 <null> 1 (native) /bin/ls
Without this patch, additional inferiors can be added, but not
properly controlled.
gdb/ChangeLog:
* nbsd-nat.h (nbsd_nat_target::supports_multi_process): New
declaration.
* nbsd-nat.c (nbsd_nat_target::supports_multi_process): New
function.
