Add a "system features" framework that will eventually be used to
automatically supply missing "basic" headers and libraries from an
older system, e.g. IRIX 5.x or Interix or AIX, etc.
Example usage:
USE_FEATURES+= snprintf glob regex
For now, we just pull in libnbcompat to supply the missing bits.
