bfd/ChangeLog:
* elfxx-riscv.c (riscv_supported_std_z_ext): Add Zama16b.
gas/ChangeLog:
* NEWS: Mention Zama16b.
* testsuite/gas/riscv/march-help.l: Add Zama16b.

Hi all,
I noticed that using -march with zama16b on current trunk triggers an
assembler error(https://godbolt.org/z/ed1EdfaKr). GCC has supported the
extension but it seems that the binutils misses it.
