There are some flavors of MIPS ABIs, such like r6 vs legacy,
nan2008 vs nan1985 etc.
The `cc -r` may not produce the correct elf binaries.
So let's skip this test for MIPS.
Many toolchain did not change the definition of NULL to avoid introducing
breaking changes in existing codebases. For example, on Windows NULL is
0 (int) regardless of the C++ standard in use.
Fixes the following warnings on CLang when compiling for Windows:

The C standard does not specify whether the underlying type of an enum
is signed or unsigned, and until C23 there was no way to control this
explicitly. GCC appears to make enums unsigned unless there is a
negative value among cases of the enum, in which case it becomes signed.
MSCV appears to make enums signed by default.
A bitfield of an enum type (which is not specificied in the C standard
either) behaves as if it was an instance of a numeric type with a
reduced value range. Specifically, a 'signed int val : 2;' bitfield will
have the possible values of -2, -1, 0, and 1, with the usual wraparound
behavior for the values that don't fit (although this too is
implementation-defined).
This causes the following issue, if we have:
typedef enum
{
G_ZERO,
G_ONE,
G_TWO
} GFoo;
struct _GBar
{
GFoo foo : 2;
};
and then assign bar.foo = G_TWO and read it back, it will have the
expected value of 2 (aka G_TWO) on GCC, but a value of -2 (not matching
any of the enum variants) on MSVC.
There does not seem to be any way to influence signedness of an enum
prior to C23, nor is there a 'unsigned GFoo foo : 2;' syntax. The only
remaining options seems to be never using enums in bitfields, which is
what this change implements.

This triggered a warning from the CHERI compiler since the struct contains
a `void *` but `__attribute__((aligned(8))` reduced alignment to less than
the `void *` alignment (which is 16 for Arm Morello).

This should not result in any functional changes, but will eventually
allow glib to be functional on CHERI-enabled systems such as Morello.

It’s not actually needed on any platform, and causes compilation
problems on platforms where it’s not available.

Fixes: #3111
The Comment field provides a user-visible description of the app,
which usually contains generic words ("and", "or", "not", "is", ...)
that add noise when used for search.
It made some sense to match against the field as a fallback for
Keywords, before that key was well established. However that key
has been around for years now, so hopefully every app where additional
terms are helpful uses it by now.
With that, the downside of added noise outweighs the benefit, so
it's time to stop matching on comments.
When setting the file time using utimensat, don't ignore
microseconds for access/modify times. By doing that, they're preserved
when using g_file_info_set_modification_date_time and then setting the file's
attributes from it.
Fixes#3116
Commit 9e2ad88455 improved app search results by allowing to differentiate
their match_type: prefix match or substring match; while giving more priority
to prefix matches over substring matches, but only when they are in the same
match_category[1].
This was a step forward but, as outlined in #3082, still not enough to get
most relevant results first to the user, because apparently (and for the
specific case of desktop app searching) a prefix match in a lower category
is more relevant to the user than a substring match in a higher category.
So that's what this commit implements, i.e. it makes sure prefix matches
are still preferred over substring matches but this time not only when
in the same category but also across different categories.
[1] Match category is the Desktop file key where the match happened.
They are shown below from top to lesser priority.

· Add a usage output that is printed when called with no argument
or with '--help' argument. This is helpful as it avoids having
to read the source code to know how to run the different options.
· Adds new '--should-show-only' option to 'search' command, to
better mimick the gnome-shell app search, by not returning
apps with NoDisplay=true.
Example for running a desktop app search with the new option from
inside the GLib build dir:
$ gio/tests/apps search --should-show-only settings
