It is about elf checking (attribute) and seem has been upstream to GCC. https://patchwork.ozlabs.org/cover/1040998/
So that patch affects GCC's "-march" string? But why do we need adjust the "riscv,isa" string in DT?
We will use this to check user program (binutils will assign this string) when it run in kernel at run time.
