AC_C_CONST was marked as an obsolescent macro back in autoconf 2.60. This
is also a target library so we know it is being built by a good C compiler.
Drop off_t search. Nothing here uses off_t..
Drop unused sizeof checks. We didn't look at their results.
libdecnumber/ChangeLog:
PR bootstrap/112422
* config.in: Regenerate.
* configure: Regenerate.
* configure.ac: Drop AC_C_CONST use.
Drop unused sizeof checks.
Drop off_t search.
