The use case for this is `make check-tcg EXTFLAGS="-accel kvm"`,
which allows validating the system TCG testcases on real hardware.
EXTFLAGS name is borrowed from tests/tcg/xtensa/Makefile.softmmu-target.
While at it, use += instead of = in order to be consistent with the
other architectures.

Both the report() function as well as the initial gdbstub test sequence
are copy-pasted into ~10 files with slight modifications. This
indicates that they are indeed generic, so factor them out. While
at it, add a few newlines to make the formatting closer to PEP-8.

The reason the ppc64 and s390x test where failing was because gdb
hides them although they are still accessible via regnum. We can
re-arrange the test a little bit and include these two arches in our
test.
We also need to be a bit more careful handling remote-registers as the
format isn't easily parsed with pure white space separation. Once we
fold types like "long long" and "long double" into a single word we
can now assert all registers are either listed or elided.

We already do a couple of "info registers" for specific tests but this
is a more comprehensive multiarch test. It also has some output
helpful for debugging the gdbstub by showing which XML features are
advertised and what the underlying register numbers are.
My initial motivation was to see if there are any duplicate register
names exposed via the gdbstub while I was reviewing the proposed
register interface for TCG plugins.
Mismatches between the xml and remote-desc are reported for debugging
but do not fail the test.
We also skip the tests for the following arches for now until we can
investigate and fix any issues:
- s390x (fails to read v0l->v15l, not seen in remote-registers)
- ppc64 (fails to read vs0h->vs31h, not seen in remote-registers)

The stack array is only referenced from the start-up code (which is
shared between the s390-ccw.img and the s390-netboot.img), but it is
currently declared twice, once in main.c and once in netmain.c.
It makes more sense to declare this in start.S instead - which will
also be helpful in the next patch, since we need to mention the .bss
section in start.S in that patch.
While we're at it, let's also drop the huge alignment of the stack,
since there is no technical requirement for aligning it to page
boundaries.
