toolchain: gcc: backport inline subword atomic support for riscv

RISC-V has no support for subword atomic operations; code currently
generates libatomic library calls.

This patch changes the default behavior to fast inline subword atomic
calls that do not require libatomic.

(cherry picked from commit 7b4a966de88aa0e1f9b7faa62a4d6cb7b01e9f8f)
