[PATCH v4 10/12] RISC-V/gas: warn about non-power-of-2 stack-align attribute
This patch adds a warning to the RISC-V GNU Assembler (gas) when the .attribute stack_align directive is used with a non-power-of-2 value. This ensures that developers are informed about potentially invalid alignment settings, which could lead to incorrect behavior or performance issues.
