Introduce per-package shared-library enabling in gcc/libgcc

Libtool supports --enable-shared=foo,bar,baz to get shared libraries
enabled only in packages foo, bar and baz. GCC's configure wouldn't
support such arguments to --enable-shared. With this patch, it does,
so it is possible to --enable-shared=libstdc++-v3, for example, so as
to avoid building a shared libgcc.
I'm checking this in head and branch. Tested on i686-pc-linux-gnu and
a number of other platforms.

enabling.
