Patch 14 in the main binutils package is applied only if a ppc64le package is being built. But since its effects are only felt if the LD_FORCE_LE envvar is set, that shouldn't be a problem - but it *will* also affect non-ppc64le arches if that is set. Other than that, there doesn't seem to be anything that would prevent me from creating a ppc64le-capable binutils. cross-gcc is another matter, but I'll deal with that in bug 1255946.

Actually, there's nothing else, not even in gcc. I'm confusing this with another binutils cross-compiler for RHEL. Do we have a preference for making one powerpc binutils/gcc that does both, or separate BE and LE ones? cross-binutils-2.25.1-1.fc23 has been submitted as an update to Fedora 23. https://bodhi.fedoraproject.org/updates/FEDORA-2015-14239 cross-binutils-2.25.1-1.fc23 has been pushed to the Fedora 23 testing repository.

Per discussion on #fedora-ppc it seems the current cross-{binutils,gcc} lack the little endian powerpc targets, please add them. <benh> hey <benh> somebody knows if the ppc64 cross compile in x86 fedora can do LE ? <benh> powerpc64-linux-gnu-ld: unrecognised emulation mode: elf64lppc <benh> Supported emulations: elf64ppc elf32ppc elf32ppclinux elf32ppcsim <sharkcz> benh: hi, yes, the cross binutils/gcc spec files have no mention about LE as target, can you please open a bug to add it? <benh> sharkcz: it works if I just use -m elf64ppc and -EL <benh> sharkcz: so not sure it's actually a problem, but it's certainly a difference vs. what's in ubuntu <sharkcz> the native LE ld lists ld: supported emulations: elf64lppc elf32lppc elf32lppclinux elf32lppcsim elf32_spu elf32ppclinux elf32ppc elf32ppcsim elf64ppc - so I think we should add LE as a target to the cross-tools too <sharkcz> does it understand ELFv2 in the current state? <benh> sharkcz: it seems to, my stuff works once built <benh> sharkcz: but yeah it looks like it should still probably be fixed
