Floating-point type _Float16 added in gcc-16 on s390 now requires
decimal floating-point support enabled in the toolchain [1][2].
Without decimal floating-point, gcc 16.2.0 fails to build with:
../../../libgcc/config/s390/_dpd_sd_to_hf.c:27:25: error: decimal floating-point not supported for this target
27 | HFtype __dpd_truncsdhf (_Decimal32);
| ^~~~~~~~~~
../../../libgcc/config/s390/_dpd_sd_to_hf.c:31:16: error: decimal floating-point not supported for this target
31 | force_convert (_Decimal32 x)

../../../libgcc/config/s390/_dpd_hf_to_td.c:34:1: error: decimal floating-point not supported for this target

../../../libgcc/config/s390/_dpd_sd_to_hf.c:35:18: error: decimal floating-point not supported for this target

Enable decimal floating-point support as suggested by Alexander
Egorenkov.
