Hmm. There isn't really a "good" way to do this. I can think of two options:
1) Modify the OpenSSL source (perhaps in the way that you suggest with a
compile time macro)
2) Provide a "dummy" implementation of netinet/sctp.h. This would have
to provide "stub" implementations of any SCTP related functions/macros
used by bss_dgram.c. That would enable you to build unmodified OpenSSL
