[PATCH v3 0/9] target/ppc: add support to disable-tcg

[Bruno Larsen (billionai)]

This patch series finishes the the changes required to support disabling
TCG for ppc targets.

With the current version of the patch, the project compiles and runs ok,
but we need some more testing to ensure that no regressions happened,
especially with relation to gdb.

For patch 7, if we were to avoid ifdef'ing the header files, we'd need
to change the configure script, and we wanted to restrict the amount of
subsystems touched. We can add it to the list of future cleanup if
everything is merged.

Based-on: <20210518201146.794854-1-richard.henderson@linaro.org>

Changelog for v3:
 * undone split, since rth's patch fixes what we needed
 * changed commit message for patch 1
 * added some fixes suggested by dgibson for patch 7

Changelog for v2:
 * split the patch series
 * added a fix for 5d145639e, which no longer compiles with linux-user
 * removed patches ther were already accepted
 * applied rth's cleanup to ppc_store_sdr1
 * changed destination of ppc_store_msr
 * undone change to helper-proto, now fewer files include it
