Currently, the introspection data for GLib and its sub-libraries is
generated by gobject-introspection, to avoid the cyclic dependency
between the two projects.
Since gobject-introspection is generally available on installed systems,
we can check for its presence, and generate the introspection data
directly from GLib.
This does introduce a cyclic dependency, which is why it's possible to
build GLib without introspection, then build gobject-introspection, and
finally rebuild GLib.
By having introspection data available during the GLib build, we can do
things like generating documentation; validating newly added API; and
close the loop between adding new API and it becoming available to non-C
consumers of the C ABI (i.e. language bindings).
Commit f6c40b1d fixed libelf detection on FreeBSD (where the library has
no pkg-config file and needs to be found via `find_library()`), but
broke `-Dlibelf=disabled` on Linux, as `get_option('libelf')` was no
longer checked.

Fixes: #3120
Add a default modification timestamp flag to g_file_copy so that it
doesn't copy the modification time from the source file as it does by
default. Similarly to G_FILE_COPY_TARGET_DEFAULT_PERMS, this flag
overrides the G_FILE_COPY_ALL_METADATA flag.

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.
