We only include them where we actually need them and only on linux.

glibc now supplies these (compatible) structs instead of including the
kernel's <asm/ptrace.h> header, so let's use them. Annoyingly this will
cause new elfutils to FTBFS on old glibc, and vice versa. So include a
new configure check for the new struct names and use the old ones if
they are not avilable.

Add the initial register setup for AARCH64 running ARM code (so
called compat mode). This makes 'eu-stack -p' happy on ARM binaries
while running on a AARCH64 kernel.

This allows CFI unwinding for ARM. It relies on having .debug_frame around
which is always the case in our testsuite. All native backtrace tests PASS
on arm if debuginfo (for glibc) is installed on the system. Otherwise the
tests SKIP.
For non-debug unwinding ARM uses EXIDX tables, not .eh_frames, which
would have to be translated to CFI to do unwinding without .debug_frame
available.
