[PATCH] libgcc: Export i386 symbols added after GCC_7.0.0 on Solaris [PR113700]

[Rainer Orth]

As reported in the PR, all libgcc x86 symbol versions added after
GCC_7.0.0 were only added to i386/libgcc-glibc.ver, missing all of
libgcc-sol2.ver, libgcc-bsd.ver, and libgcc-darwin.ver.

This patch fixes this for Solaris/x86, adding all of them
(GCC_1[234].0.0) as GCC_14.0.0 to not retroactively change history.

Since this isn't the first time this happens, I've added a note to the
end of libgcc-glibc.ver to request notifying other maintainers in case
of additions.

Tested on i386-pc-solaris2.11.

Ok for trunk?
