I'm fine with that, but it just introduces another configure option for
people to learn about. If we have to teach people something, I'd rather
teach them to use --disable-shared when they build the libraries
themselves.

There is no problem when the support libraries are built as part of the
gcc source tree, because in that case the build system automatically
configures them with --disable-shared.
