Is it possible to compile gcc 8 from the latest sdk source with the previous sdk installed with gcc 6?

It errors (after hours.....) on cfi assembly directives with an unknown pseudo-op errors (.hidden .cfi_startproc .cfi_endproc)

Wondering if I did something wrong, or it only compiles under the latest sdk installed.
