It's unlikely anybody is very interested in gcc-10 as there will only be
one more release from that branch, and most of these are just harmless
cases of unclear output. The configure script works correctly, it just
prints jumbled output.

This is perfectly normal, __int128 is supported when building 64-bit
libraries and not when building 32-bit libraries.

Libquadmath provides routines for working with 128-bit floating-point
types, not integers.
