Build failure here. I have ubuntu 22.04,

crossbuild-essential-riscv64/jammy,jammy,now 12.9ubuntu3 all [installed]

Yeah, that was intentional. In theory a softmmu target is freestanding and
does not need anything beyond the compiler install, so configure defaults
to the native compiler, which is biarch. That however assumes that the
compiler install includes the libgcc for both architectures.
Does that mean that Ubuntu installs GCC without a 32-bit libgcc.a?

I think they package it in a separate package, eg lib32gcc-9-dev
(adjust package name to suit gcc version).

It's there, as Peter says, but it's not installed with the build-essential meta-package,
and the crossbuild-essential-i386 package installs a different libgcc.

Ok I will try using ld -r to detect the presence of libgcc.
