rlm_wimax doesn't need a configure script either.

OTP configure arguments should be altered to match --with-openssl-include-dir and --with-openssl-lib-dir as it
need to check for additional newish libssl functions.

rlm_unbound doesn't need to check for libssl headers either it's not using anything special. files should inherit top level CPPFLAGS.

modules which need to link against libssl should add OPENSSL_LIBS to their LDFLAGS.

I'll make the changes...
