[committed] correct %D quoting in gcc/config/sol2-c.c

[Martin Sebor]

In preparation for committing the meat of the patch for bug 80280
I've committed the following in r247758 as an obvious fix to prevent
the new -Wformat warning from breaking Solaris bootstrap.  Bootstrap
is currently broken due to 80673 (that looks like a separate issue
from the warning).
