Here is the proposed minimum patch to default to --enable-threads=posix
unless either some other --enable-threads option or --disable-threads
is given on Linux. I don't see why somebody might want not to build thread
aware gcc/libstdc++ by default.
I've verified that configure with --disable-threads gives the configuration
which used to be, ie. no thread support and that no --*threads option given
to configure causes posix threads to be used.
Ok to commit to mainline/3.2 branch?

to configure.
