I previously refactored config.sub to parse 'basic_machine' into
separate 'cpu' and 'vendor' variables. This is a kindred refactor
where 'basic_os' (a rename of 'os' when used early on) is now parsed
into 'kernel' and 'os'.
Like the previous refactoring, this does make things a bit longer. I
think the change makes the code easier to understand and more robust,
so it is worth the cost of a longer script.

overrides.
Previously, 'ibm' was forced, which caused problems when someone
wanted to use 'busybox' as a vendor and cross-compile with a slightly
different toolchain. The fix changed behaviour such that without any
vendor, it would use to 'unknown' rather than 'ibm' as before.
This patch aims to compromise between the old and new behaviour by
making 'ibm' a default for those CPUs when no vendor is specified, but
if the user explicitly provides a vendor that is used instead. This
sort of "vendor defaulting" has plenty of precedent in config.sub, so
it seemed like a good approach.

ultimately governs what the native ABI is.

config.guess expected triplet through config.sub so that we can check
that it is properly recognised. Sometimes, new triplets have been
added to config.guess without updating config.sub accordingly (eg,
Harris NightHawk machines running PowerUnix from the mid-1990s!)
* config.sub (case $os): Match nsk* and powerunix. Don't later
match nsk* and set os=nsk which removes the OS version number.

New test.
system compiler is installed. If not, do not run set_cc_for_build,
as the default cc will open a dialog box asking to install
Xcode. If no C compiler is available, guess based on uname -p and
uname -m.
* testsuite/config-sub.data: Add test cases for wasm (Web Assembly) and
wasi (Web Assembly System Interface).

uname replacement to './uname', not 'uname'.
