The makefile inside 'tools' directory already has a default value of
'M'.

Linux being an object orientd code, reuses the code wherever possible.
Thus, there are cases where two completely independent and different
structures might have a member which has same structure template.

For example, in objects.c, in function "__ti_create",
	- trig->head.name, and
	- cset->zdev->head.name

are of same type, but belong to different structures. And when the code
tries to copy/ write one into another, we get truncation warning.

And in this case we cannot even increase the size of only one, because
both the members are created from same structure.

Thus, one good solution is to not to treat those warnings as errors.

Variable name 'LINUX' is very ambiguous for its purpose in the makefile.
Also, this project builds as a part of COHT project which uses another
variable name 'KERNELSRC' for the same purpose. Hence, this change makes
this project uniform with others.

`struct timespec` is no longer available from headers after kernel 5.6.
It is now required to use `struct timespec64`, which uses a 64bit
integer for seconds instead of the former 32bit.

The function `timespec_to_ktime` becomes `timespec64_to_ktime`

The function `getnstimeofday` becomes `ktime_get_real_ts64`

At some point I renamed doc into Documentation but there are projects
out there who test the presence of doc/ to build 'zio'.

We should fix the Makefile in all these projects but right now it is not
that easy and this is the easiest fix to make the CERN COHT building mechanism
working again.
