NetBSD cannot successfully run "ensurepip" without access to the pyexpat

This patch is meant to ensure that console entry point scripts will

This patch changes the configure script so that it always creates a

Several debian-based tests need the python3-venv dependency as a

This patch changes how we detect and install meson.
The previous patch creates a lightweight Python virtual environment
unconditionally using the user's configured $python that inherits system
packages. If Meson is installed there and meets our minimum version
requirements, we will use that Meson.
NetBSD debundles pyexpat from python, but ensurepip needs pyexpat. Try
our best to offer a helpful error message instead of just failing
catastrophically.

This patch introduces the RISC-V Zfa extension, which introduces
additional floating-point extensions:
* fli (load-immediate) with pre-defined immediates
* fminm/fmaxm (like fmin/fmax but with different NaN behaviour)
* fround/froundmx (round to integer)
* fcvtmod.w.d (Mod
