The current api from safe_syscall_base() is to return -errno, which is
the interface provided by *some* linux kernel abis. The wrapper macro,
safe_syscall(), detects error, stores into errno, and returns -1, to
match the api of the system syscall().
For those kernel abis that do not return -errno natively, this leads
to double syscall error detection. E.g. Linux ppc64, which sets the
SO flag for error.
Simplify the usage from C by moving the error detection into assembly,
and usage from assembly by providing a C helper with which to set errno.

The only difference between the two, as far as either configure or
Meson are concerned, is in the multilib flags passed to the compiler.
For QEMU, this fixes the handling of TYPE_OLDDEVT in
include/exec/user/thunk.h and enables testing of dirty ring buffer,
because both are using HOST_X86_64.
For tests/tcg, this means that on a hypothetical x32 host the
cross compiler will not be used to build the tests.

The only difference between the two, as far as either configure or

For tests/tcg, specify the endianness explicitly on the command line;
for configure, do the same so that it is possible to have --cpu=ppc64le
on a bigendian system or vice versa. Apart from this, cpu=ppc64le can
be normalized to ppc64 also in configure and not just in the meson
