Are you assuming that downstream distributions would ensure that
gcc/binutils would have HLE support before building a glibc that
needs it rather than use a opcode compat layer like hle.h?
I would agree with that assumption.
The addition of hle.h seems more to allow developers to play with
HLE without needing to upgrade their tools; useful, but only for
the small subset that are doing that and not for the project as a
whole.
