[patch] Fix target-async SIGTTOU stop (PR 12260)

[Jan Kratochvil <jan.kratochvil@redhat.com>]

Hi,

it is difficult to play with `set target-async on' as it usually SIGTTOU stops
at various places.
http://sourceware.org/bugzilla/show_bug.cgi?id=12260

$ ./gdb -nx -ex 'set target-async on' -ex start ./gdb
[...]
Starting program: .../gdb/gdb 
[1]+  Stopped                 ./gdb -nx -ex 'set target-async on' -ex start ./gdb

If it has a regression it IMO only means there is missing
target_terminal_inferior call at some other place.

No regressions on {x86_64,x86_64-m32,i686}-fedora16pre-linux-gnu.  But I was
unable to reproduce the problem under DejaGnu so the regression test may not
be meaningful.

Not going to check it in without a review.


Thanks,
Jan
