Update the Interix default build configuration.

Update the Interix default build configuration.

Currently, on Interix, libsuacomp is required for building (see [1]).

Since suacomp provides poll() and inttypes.h for all interix versions,
remove NO_*=YesPlease that are no longer necessary.

Interix versions 3 and 5 miss struct sockaddr_storage, so make git
avoid using it.

Same for FNMATCH_CASEFOLD, which does not exist for Interix 3 and 5.
