Please, include support to powerpc (32bits) on fchroot.

We need change use to enable QEMU_SOFTMMU_TARGETS=ppc and QEMU_USER_TARGETS=ppc with:

>=app-emulation/qemu-6.2.0-r3 qemu_user_targets_aarch64 qemu_user_targets_arm qemu_user_targets_riscv64 static-user qemu_user_targets_ppc64 qemu_user_targets_ppc qemu_softmmu_targets_ppc

I have successfully built boostrap using FFS optimized for PowerPC-G4 (PPC 74xx) PPC 7450 family Compatible processors are Motorola/Freescale MPC7450, MPC7440, MPC7451, MPC7441, MPC7455, MPC7445, MPC7457, MPC7447, MPC7447/A and MPC7448.

I used the following steps:

1- I created this yaml file on ~/ffs/profiles/gnu/arches/powerpc.yaml:

arch:
  cflags: -mcpu=7450 -O2 -maltivec -mabi=altivec -fno-strict-aliasing -pipe
  arch: powerpc
  musl_lib_arch: powerpc
  target: powerpc-unknown-linux-gnu

    NOTE:  optimized to cpu G4 (PPC 74xx) PPC 7450 family Compatible processors are Motorola/Freescale MPC7450, MPC7440, MPC7451, MPC7441, MPC7455, MPC7445, MPC7457, MPC7447, MPC7447/A, and MPC7448.

2- I needed to alter the versions of some software in the FFS gnu since musl was not able to build the GCC for this architecture on file ~/ffs/profiles/gnu/sources.yaml:

• gcc-12.1.0
• glibc-2.35
• diffutils-2.38

3- I built a complete native toolchain and starter environment with gnu libc:

user $ sudo emerge -v pyyaml jinja
user $ git clone https://code.funtoo.org/bitbucket/scm/core/ffs.git
user $ cd ffs
user $ bin/sourcer gnu fetch
user $ bin/builder gnu powerpc cross_tools
user $ bin/builder powerpc tools

Work like a charm! Thanks drobbins for creating this fantastic tool that is FFS
