Do you need the LDAP routines? You could also try to minimize the amount of
features available in libcurl to make it more easily build statically.

I've recently statically build libcurl with success and stripped the feature
with the configure flags down to HTTP(S), SSL and proxy support. All the
rest was overhead to me with complicated the static building a lot.
