[RFC PATCH 0/4] target/ppc: add disable-tcg option

["Bruno Larsen (billionai)" <bruno.larsen@eldorado.org.br>]

This patch series aims to add the option to build without TCG for the
powerpc target. This RFC shows mostly the strategies employed when
dealing with compilation problems, and ask for input on the bits
we don't quite understand yet.

The first patch mostly code motion, as referenced in 2021-04/msg0717.
The second patch shows the 2 strategies we've considered, and hope to
get feedback on. The third patch contains the stubs we haven't decided
on how to deal with yet, but needed to exist to compile the project.
The final patch just changes the meson.build rules

  target/ppc: Code motion required to build disabling tcg
  target/ppc: added solutions for problems encountered when building
    with disable-tcg
  target/ppc: Add stubs for tcg functions, so it build with disable-tcg
  target/ppc: updated build rules for disable-tcg option
