Having arm 32/64 bit headers coexisting turns out to be tricky. Unfortunately
our wrapper works using wordsize.h and this differs on arm so we can't use it.
Therefore replicate the logic here for arm. I did look into writing our
own wordsize.h but we also need to remap kernel headers on arm and
since wordsize.h comes from libc, that doesn't work for kernel headers.

Much as with -native recipes, as addressed in commit
b15730caf0d4c40271796887505507f2501958bb, arch specific variables
like MIPSPKGSFX_ABI were affecting -nativesdk sstate checksums for
recipes like nativesdk-glibc-initial.
Disable multilib_header for nativesdk as we don't use multilibs in
this scenario.

musl is not multilib and this creates trouble. eg. when
util-linux probes for ncurses it does not find it because
ncurses has installed the multilibbed header and this
header includes bits/wordsize.h and this header does not
exist on musl systems. If and when musl adds multilib
support we will revisit it.

The use of arch specific variables like MIPSPKGSFX_ABI was creeping
into the -native sstate checksums of package like ncurses-native.
This is pointless and undesireable. We could add specific variable
exclusions but we might as well just brute force the code to be disabled
in the -native case since we don't use multilibs in the native case.

The n32 architecture is odd, in that it's a mips64 ABI which happens
to be 32-bit. To handle this, we need something in the environment
which can be used to distinguish it. The obvious place to stash this
is the ABI suffix, so we use "n32" as an ABI suffix. This allows
a couple of improved checks:
1. In insane.bbclass, we can use "linux-gnun32" to discern that it's
okay for a mips64 binary to be a 32-bit binary in some cases.
2. In multilib_header, we can check for the n32 ABI, and use a distinct
value.
3. In siteinfo, add linux-gnun32 as a synonym for linux, similar to
what's done for linux-gnux32, and tell the mips*-linux-gnun32 variants
to pick up the corresponding mips-linux site configs.
Note that the multilib header wrapper already has n32 hooks in it, there
was just nothing creating -n32 header variants.

This helper function and associated header will allow us to
resolve two/three header files that conflict due to contents
that change based on wordsize and ABI.
