GCC was changed this behavior almost 10 years ago: https://gcc.gnu.org/pipermail/gcc-patches/2015-August/426507.html .
The reason is because GNU binutils and GCC are seperate projects so an older binutils can be used with a newer GCC without any issues. Plus it allows for GCC to use a different assembler besides GNU binutils which might not have that specific -mcpu option.
clang should do the same.
Right now `-no-integrated-as -mcpu=oryon-1` is broken when using with clang and GNU binutils' as because of this . `oryon-1` was not added to GNU binutils because it was not needed for when use with GCC; in fact there are other most other `-mcpu=` options have not been added to GNU binutils for this same reason.
