[PATCH v2 00/15] configure cleanups for QEMU 8.2

[Paolo Bonzini <pbonzini@redhat.com>]

This includes a few more patches cleaning up the configure/meson
separation.  The highlights are fixing --host-cc, removing the last
traces of compiler detection from config-host.mak, and dropping the
useless pc-bios/Makefile.

Compared to v1, I have also removed the loop that takes random CONFIG_*
lines of config-host.mak and shoves them into config-host.h.  These were
the last remains of the old scripts/create_config logic, but they are not
needed anymore because all config-host.h tests are done in meson.build or
come from meson-level options.  We're definitely getting into diminishing
returns land (which is a good thing), but I believe it's worth having a
few extra patches to further reduce the coupling between config-host.mak
and meson.build.

To be honest, the plugin code would probably be a lot simpler if
contrib/plugins/Makefile was turned into a meson.build file.  As things
stand, the "are plugins enabled?" logic has to stay in configure, in order
to decide whether to build contrib/plugins.  However, contrib/plugins
was left as a separate build process for demonstration purposes, so I
am not going to change that.  If desired, this can be changed in the
future (together with moving all the $plugins logic from configure
to meson.build).  Perhaps the "external project" module from Meson
could be used too, but right now it is limited to projects with
a "configure" phase.
