We support this in a machine file:
```
[binaries]
pkgconfig = 'pkg-config'
pkg-config = 'pkg-config'
```
and you can use either one, because internally we look up both. If you
only set *one* of them, this plays awkwardly with setting $PKG_CONFIG,
since we don't know which one you set in the machine file and the
*other* one will be initialized from the environment instead.
In commit 22df45a31981874310a78dde0df59a6a7c5ebb29 we changed program
lookup of config-tool style dependencies to use the regular tool names
and only fall back on the strange internal names. This affected the
pkg-config class too.
The result is that instead of preferring `pkgconfig =` followed by
$PKG_CONFIG followed by `pkg-config =`, we inverted the lookup order.
This is a good idea anyway, because now it behaves consistently with
`find_program('pkg-config')`.
Unfortunately, we documented the wrong name in a bunch of places, and
also used the wrong name in various testsuite bits, which meant that if
you set $PKG_CONFIG and then ran the testsuite, it would fail.
Correct these references, because they are buggy.
One test case expected to find_program() a native copy for convenience
of testing against natively installed glib. Force it to resolve a native
copy.

c_args are meant to be overridden by the user if needed (even via the
environment CFLAGS variables + -Doptimization=plain, for example),
so they should not contain any option that affect the multilib search
path. For example, a hypothetical native file like this:
[binaries]
c = gcc
[built-in options]
c_args = ['-m32']
would *not* build 32-bit binaries if -Dc_args is passed to meson.
Such options, instead should be in the [binaries] section. Adjust
the sample cross files included with meson.

This is like the project options, but for meson builtin options.
The only real differences here have to do with the differences between
meson builtin options and project options. Some meson options can be set
on a per-machine basis (build.pkg_config_path vs pkg_config_path) others
can be set on a per-subproject basis, but should inherit the parent
setting.

* environment: Fix passing always args to a number of less common linkers
These are mostly (oops xilink) proprietary linkers I can't use for
various reasons.
Fixes: #6332
* Add intelfix from scivision.
* Ifort fix from scivision.
* PGI fix from scivision.
* Cuda fix from scivision.
* Fix linker passing for armclang.
