disable incredibly impractical clang-tidy check
...
bugprone-easily-swappable-parameters is completely impractical for real
world usage. It's a reasonable thing to consider as part of API design
but it mostly applies to having APIs taking a lot of parameters. It's
unreasonable to disallow APIs simply taking 2 integer parameters even as
a loose guideline.

Fix CPPFLAGS in test Makefile
...
In particular, the _GNU_SOURCE feature test macro needs to be set in
order to correctly define mmap(2) flags such as MAP_ANONYMOUS.
Otherwise, compilation of some test files fails when CPPFLAGS is not
defined in the initial user environment, as Make then does not export it
from the root Makefile to the sub-make.
