[PATCH v4 12/12] RISC-V/bfd: warn about non-power-of-2 stack-align attribute
This patch introduces a warning for non-power-of-2 values used with the RISC-V stack_align attribute, enforcing sensible alignment. It also refactors some conditional logic for clarity. The change ensures that only power-of-2 alignment values are accepted, promoting correct code generation.
