Future releases of GCC are planning to remove[0] default support for
some old features that were removed from C99 but GCC still accepts.
We can test for these changes by using the following -Werror=
directives
-Werror=implicit-int
-Werror=implicit-function-declaration
-Werror=int-conversion
-Werror=strict-prototypes
-Werror=old-style-definition
Doing so revealed an issue with the auto/ tests in that the test
programs always define main as
int main()
rather than
int main(void)
which results in a bunch of errors like
build/autotest.c:3:23: error: function declaration isn't a prototype [-Werror=strict-prototypes]
3 | int main() {
| ^~~~
build/autotest.c: In function 'main':
build/autotest.c:3:23: error: old-style function definition [-Werror=old-style-definition]
The fix was easy, it only required fixing the main prototype with
find -type f -exec sed -i 's/int main() {/int main(void) {/g' {} \;
Regardless of these upcoming GCC changes, this is probably a good thing
to do anyway for correctness.

This variant will be more interoperable across various systems
and it's already used in Ruby module.
Otherwise, configure tests fail on NetBSD with:
gcc: Missing argument for -Wl,-rpath
Now it's possible to disable default bind mounts of
languages by setting:
{
"isolation": {
"automount": {
"language_deps": false
}
}
}
In this case, the user is responsible to provide a "rootfs"
containing the language libraries and required files for
the application.
Since the introduction of rootfs feature, some language modules
can't be configured multiple times.
Now the configure generates a separate nxt_<module>_mounts.h for
each module compiled.
Currently almost all Unit object files depends on generated nxt_version.h.
This patch adds missing dependence and fixes running make with multiple
jobs.
This closes#318 issue on GitHub.
