Can't interrupt process without controlling terminal on Solaris (PR gdb/8527)
If gdb attaches to a process that either has no controlling terminal,
or the controlling terminal differs from the one gdb is running under,
break/^C doesn't interrupt the debugged process on Solaris.
Fixed as follows, analogous to what all all other targets do. Patch from
the PR, recently re-submitted by Brian Vandenberg.
Tested on amd64-pc-solaris2.11, sparcv9-sun-solaris2.11, and
x86_64-pc-linux-gnu.
