Add configure check for std::thread
This adds a configure check for std::thread. This is needed because
std::thread is not available on some systems, like some versions of
mingw and DJGPP.
This also adds configury to make sure that a threaded gdb links
against the correct threading library (-lpthread or the like), and
passes the right flags (e.g., -pthread) to the compilations.
Note that this also links gdbserver against the thread library. This
is not strictly necessary at this point in the series, but a later
patch will change gdbsupport to use pthread_sigmask, at which point
this will be needed.
