No, not as =E2=80=9Csupported=E2=80=9D, I surely don=E2=80=99t want to deal= with mips64el-linux bugs. :-) > Current text: > > @item mips64el-linux (deprecated)=C2=AC > little-endian 64-bit MIPS processors, specifically the Loongson series, > n32 ABI, and Linux-Libre kernel.

Maybe it=E2=80=99s more readable to keep it as a bullet list, like: @item mips64el-linux (@emph{unsupported}) =E2=80=A6 @item powerpc-linux (@emph{unsupported}) =E2=80=A6 with a sentence explaining what =E2=80=9Cunsupported=E2=80=9D means. IMO guix.m4 should either require --with-courage or emit a prominent warning for these. WDYT? Thanks, Ludo=E2=80=99.
