You can probably get away with overriding lt_prog_compiler_pic, lt_prog_compiler_pic_CXX, ..., in configure.ac, when doing it *after* the AC_PROG_LIBTOOL aka LT_INIT invocation, and before either of AC_OUTPUT or LT_OUTPUT. However, this is not recommended, doing this will let configure test the wrong pic_flag (i.e., the one it sets rather than your override), and if this breaks now or in a later release you get to keep the pieces. We should probably change the code so that the override can be done before AC_PROG_LIBTOOL, so that at least -DPIC is added consistently, and that the compile test uses the right flag.
