    system.h: add support for IBM xlc C compiler
    
    Added a section to system.h guarded with __xlc__ for the IBM xml C
    compiler. Before this change the section titled 'generic "safe guess" on
    old 32 bit style' was used, which resulted in a wrong definition of
    CURL_TYPEOF_CURL_SOCKLEN_T, and for 64-bit also CURL_TYPEOF_CURL_OFF_T
    was wrong.
    
    Compilation warnings fixed with this change:

      CC       libcurl_la-tftp.lo
    "tftp.c", line 1115.33: 1506-280 (W) Function argument assignment between
