Yep

libtool --features | grep "enable shared"

libtool --mode=compile $(CC) $(CPPFLAGS) $(CFLAGS) -c foo.c

this creates foo.lo

libtool --mode=link $(CC) $(CPPFLAGS) $(CFLAGS) $(LDFLAGS) \
foo.lo bar.lo ... -o libbaz.la -rpath $(libdir)

Then, at install time:

libtool --mode=install install -c libbaz.la $(libdir)/libbaz.la


And that's all, as long as all you want is to create a shared
library.

If you want to get this library linked into a program, you'd have to
add:

libtool --mode=link $(CC) ... x.o y.o -o prog libfoo.la

And use libtool to install the program:

libtool --mode-install install prog $(bindir)/prog
