OK, thanks. Really it is, and glibc also defines another archs (e.g. microblaze). But I guess, at present, we have to use qemu's "elf.h": - qemu may use another libc libraries (e.g. newlibc, I guess), which may not have these macros. - If qemu will consider about the system elf.h file in the future, it will change all related macros (it almost means rewrite its elf.h). So for me, at present, just follow with the current qemu's elf.h is OK: (define EM_TILEGX directly without ifdef EM_TILEGX or endif).
