$ libtool --help --mode=link | grep static
-all-static do not do any dynamic linking at all
-static do not do any dynamic linking of libtool libraries

Change the default behaviour for `AC_PROG_LIBTOOL' to disable
static libraries. The user may still override this default by
specifying `--enable-static'.

Assuming libtool is doing all your linking:
./configure LDFLAGS='-all-static'
You can find out what the magic flag for your compiler is by looking at
the AC_LIBTOOL_PROG_COMPILER_PIC in libtool.m4 (_LT_COMPILER_PIC in 2.0
alpha releases). And then you could add that manually with:
make LDFLAGS=flag-from-libtool.m4

This raises a good point. And although the static link issue comes up
occasionally, I don't use it myself and handn't thought too deeply about
it.
Does anyone use libtool's -static flag to deliberately link statically
against libtool libraries only? I would have thought that it is far
more common to want all-static behaviour.
Unless someone shouts me down, then according to the principle of least
surprise, I'm inclined to change the semantics to:
-static do not do any dynamic linking at all
-lt-static do not do any dynamic linking of libtool libraries
(We can keep -all-static as an alias to -static).
Cheers,
Gary.
