Okay, thanks.

    include: Allow for our md5.h to defer to the system header
    
    This came up in the context of libsanitizer, where platform-specific
    support for FreeBSD relies on aspects provided by FreeBSD's own md5.h.
    
    Address this by allowing GCC's md5.h to pull in the system header
    instead, controlled by a new macro USE_SYSTEM_MD5.
