Re: PPC64: gcc currently compiles for power4 by default, causing glibc's sqrtf to fail on e6500

[Bas Vermeulen <bas@daedalean.ai>]

I just checked gcc's configure, and that doesn't take --with-cpu= as an argument. It doesn't fail when it has it, but it doesn't actually do anything with it either.

So my patch would be the correct way to handle this.

So, the file you want to modify is:

> https://sources.debian.org/src/gcc-7/7.3.0-1/debian/rules2/#L380-L392

It would be nice if anyone who cares about the ppc64 could actually
post what kind of hardware they have. We should find a consensus on
where to put the baseline.

Rebuilding the whole archive isn't so much of a problem. We have already
done that :).
