Hi,

  The below patch fixes failures in builtin-snprintf-warn-3.c for the
  avr target.

  The test declares a struct with an array member that has INT_MAX/32767
  elements. This causes a "type xxx is too large" error for targets like
  the avr, which have pointers smaller or equal to (16 bit) int size.

  Fixed by marking the test as unsupported for targets with ptr size <
  32. Committed as obvious.

Regards
Senthil
