RISC-V: Add configure check for Zaamo/Zalrsc assembler support
Binutils 2.42 and before don't support Zaamo/Zalrsc. Add a configure
check to prevent emitting Zaamo/Zalrsc in the arch string when the
assember does not support it.
gcc/ChangeLog:
* common/config/riscv/riscv-common.cc
(riscv_subset_list::to_string): Skip zaamo/zalrsc when not
supported by the assembler.
* config.in: Regenerate.
* configure: Regenerate.
* configure.ac: Add zaamo/zalrsc assmeber check.
