In order to add a new architecture or sub-architecture to OE, you currently
need to tweak the table in siteinfo.bbclass. This adds a mechanism so this
can be done from a BSP layer. It needs a function definition which needs
a class file but can then be done with something like:

def rp_testfunc2(archinfo, osinfo, targetinfo, d):
    archinfo['testarch'] = "little-endian bit-32"
    osinfo['testos'] = "common-linux"
    targetinfo['mymach-linux'] = "mymach-linux-common"

    return archinfo, osinfo, targetinfo

SITEINFO_EXTRA_DATAFUNCS = "rp_testfunc2"

Found that ssize_t was being wrongly computed for mips64 musl
because it was using wrong cache files.

alias them to glibc versions, musl doesn't _yet_ have target
incompatibilities to note in siteinfo thankfully.

Add musl aliases for aarch64 and ppc64 targets

Teach siteinfo about x86_64-elf so that baremetal toolchains parse/build.

If a siteinfo enabled tasks re-executes at the wrong moment whilst something else is
in do_configure, the _config files can be removed which upsets autoconf and
causes build failures.

Use the same approach as we do for dealing with the aclocal files. We already
parse the manifests so look out any *_config files and if so, copy them, then
reference the copy from siteinfo instead. This has the advantage of also being
more deterministic.

Pull wordsize related items from arm-common and put in
arm-32.  Leave them as they were.  Copy arm-32 to arm-64
and comment out all variables.  Re-define to correct
values leaving items which do not appear to be used
undefined.

We will use '-musl' to identify musl based systems
this patch lays the foundation for recognising those
and map them to internal variable representations
