Oops, missed that, sorry.
The following patch should fix that, tested on x86_64-linux make
options-save.c (same file as before) and -> ia64-linux cross make
options-save.o (no warning anymore, just the unwanted declarations gone).

* optc-save-gen.awk: Don't declare mask variable if explicit_mask
array is not present.
