And that seems to work if I place those in my Makefile.am
$ grep -- -static src/Makefile.am
libtest_LDFLAGS = -static
(which maybe answers your question if anyone is using -static)

$ ./configure --help | grep static
--enable-static[=PKGS] build static libraries [default=yes]
I'm not using AC_DISABLE_STATIC in configure -- and using
--enable-static (without listing packages) seems to have no effect.
So do I have something setup incorrectly?

libxml2.so.2 => /usr/lib/libxml2.so.2 (0x40027000)
libpthread.so.0 => /lib/tls/libpthread.so.0 (0x40122000)
libz.so.1 => /usr/lib/libz.so.1 (0x40132000)
libswish-e.so.2 => /home/moseley/static/lib/libswish-e.so.2 (0x40144000)
libm.so.6 => /lib/tls/libm.so.6 (0x4017a000)
libc.so.6 => /lib/tls/libc.so.6 (0x4019d000)
/lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x40000000)
So, does that mean I'm not passing in a variable to my Makefile.am?

I'm not really clear on what you are asking, but I use -static in my
Makefile.am to always link a little test program with our library
statically to help with debugging.
$ ldd libtest
libz.so.1 => /usr/lib/libz.so.1 (0x40027000)
libm.so.6 => /lib/tls/libm.so.6 (0x40039000)
libc.so.6 => /lib/tls/libc.so.6 (0x4005d000)
/lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x40000000)
So libswish-e is linked statically there.

As long as "libtool libraries" is clear.
