Fixes smtp_in.c: In function ‘smtp_start_session’: smtp_in.c:1976:36: error: invalid application of ‘sizeof’ to incomplete type ‘struct options’ EXIM_SOCKLEN_T optlen = sizeof(struct ip_options) + MAX_IPOPTLEN; smtp_in.c misdetects the needed style for ip_options, only OPTSTYLE == 2 works. Since musl does not provide any macro[1] to detect it we need to pretend to be darwin in order to fix the compile bug. In order to do so we need the generated os.h before building start, therefore add some make subtargets to the configure step.
