When combining variable assignments with a shell command, some older
shells (notably heirloom-sh and presumably also Solaris 10 /bin/sh)
have a bug which causes the assignment to alter the current execution
environment whenever the command is a shell built-in. For example:
% dash -c 'x=good; x=bad echo >/dev/null; echo $x'
good
% jsh -c 'x=good; x=bad echo >/dev/null; echo $x'
bad
The config.sub script contains a few commands of the form:
IFS=- read ...
which triggers this bug, causing the IFS assignment to persist for the
remainder of the script. This can cause misbehaviour in certain cases,
for example:
% jsh config.sub i386-linux-gnu
config.sub: test: unknown operator gnu
% jsh config.sub i386-gnu/linux
sed: can't read s|gnu/linux|gnu|: No such file or directory
Invalid configuration `i386-gnu/linux': OS `' not recognized
* config.sub: Save and restore IFS explicitly to avoid shell bugs.

Some cases quote the argument to echo and some do not. At runtime
it probably does not matter because the substituted values will never
contain whitespace, but quoting them all would make shellcheck more
useful.

Recently RISC-V community got patches big-endian support for binutils,
and we'd like to accept that, however before accepting that I think it
would be better to upstream config.sub and config.guess change here :)
It's my check result on Ubuntu 18.04:
$ make check
cd testsuite && bash config-guess.sh && rm uname
PASS: config.guess checks (131 tests)
cd testsuite && bash config-sub.sh
PASS: config.sub checks (830 tests)
PASS: config.sub idempotency checks (767 tests)
PASS: config.sub canonicalise each config.guess testcase (131 tests)

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.

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.
* testsuite/config-guess.data: Tweak Unleashed test case.
* testsuite/config-sub.sh (run_config_sub_with_guess_triplets):
New test.
