Why?  (If the library is private to one package, that counts
as a reason, but see below.)

These are shared libraries.  In most cases shared libraries
are what you want.

If the library will be used only inside one package, build
it as a libtool convenience library.

Otherwise build shared, static or both depending on what the
user wants.  This works automatically, AC_PROG_LIBTOOL adds
corresponding options to configure, with the default to build
both types (provided that it's possible on the target
platform).
