You need to enable docker or podman for your development, so that you get all
of the cross-compilers.

Then:

  TEST    fcvt on arm
TODO ../qemu/tcg/tci.c:614: tcg_qemu_tb_exec()
../qemu/tcg/tci.c:614: tcg fatal error
qemu: uncaught target signal 11 (Segmentation fault) - core dumped

  TEST    float_convs on m68k
TODO ../qemu/tcg/tci.c:614: tcg_qemu_tb_exec()
../qemu/tcg/tci.c:614: tcg fatal error
qemu: uncaught target signal 11 (Segmentation fault) - core dumped

which is of course one of the TODO assertions.
It's positively criminal those still exist in the code.
