Just create a convenience library from libfoo_unshareable.

lib_LTLIBRARIES = libfoo.la
noinst_LTLIBRARIES = libfoo_unshareable.la
libfoo_la_LIBADD = libfoo_unshareable.la

Unless you want to install the static library, too.

lib_LTLIBRARIES = libfoo.la libfoo_unshareable.la
libfoo_unshareable_la_LDFLAGS = -static
libfoo_la_LIBADD = libfoo_unshareable.la
