[pushed] Remove "linux_multi_process" global

Tom Tromey-2
The "linux_multi_process" is initialized but never modified.  I
discussed this with Pedro on irc, and he said that, while it was
useful when developing this feature, it is now no longer needed.  So,
this removes it.

        * linux-nat.c (linux_multi_process): Remove.
        (linux_nat_target::supports_multi_process): Return true.
