I ran configure on my Talos II, and got the following error message.
checking for the Guix system type... powerpc64le-linux
configure: error: `powerpc64le-linux' is not a supported platform.
See "GNU Distribution" in the manual, or try `--with-courage'.
Guix already knows about this architecture, but building glibc will fail
if gcc does not have the float128 datatype. Once I saw this link[1] on
the guix mailing list, I knew how to solve the build error.
For the second question I could not find an answer.

It needs to be ppc64el I think. I will later do a test in a big endian
vm. POWER9 is a bi-endian architecture, and most distros only support
little-endian. POWER4 only supports big-endian, and is still supported
by some distros. After testing I will send an updated patch.
I don’t think that answers my questions. :-)
Those were:
1. What GNU triplet do you use?
2. What the reason for this extra configure flag, so we can add it in
the comment above in place of XXX?
TIA!
