I did exactly that yesterday as an experiment for talloc. That worked.
FWIW, the configure step takes about two orders of magniture
more time than compiling it - even if for talloc about 99% tests which
are done at configure time are useless :)

(For talloc it really is trivial to build it with just 3 commands to
build the 3 .so libs with about 5-10 -Defines for configure-generated
variables which re _actually_ used in there.  For other parts it is
not _that_ simple :) )
