Well, you can always copy its value before it's modified...  Maybe
AC_ENABLE_SHARED should be modified so as to preserve the original

Well, there are --tag disable-shared and --tag disable-static, but
indeed, there's no easy way to define them on a per-library basis.  If
that's what you want to do, I'd suggest splitting the package.
