From: Quentin Monnet <quentin.monnet@netronome.com>
Several minor fixes and harmonisation items for Makefiles:
* Use the same mechanism for verbose/non-verbose output in two files
("$(Q)"), for all commands.
* Use calls to "QUIET_INSTALL" and equivalent in Makefile. In
particular, use "call(descend,…)" instead of "make -C" to run
documentation targets.
* Add a "doc-clean" target, aligned on "doc" and "doc-install".
* Make "install" target in Makefile depend on "bpftool".
* Remove condition on DESTDIR to initialise prefix in doc Makefile.
* Remove modification of VPATH based on OUTPUT, it is unused.
* Formatting: harmonise spaces around equal signs.
* Make install path for man pages /usr/local/man instead of
/usr/local/share/man (respects the Makefile conventions, and the
latter is usually a symbolic link to the former anyway).
* Do not erase prefix if set by user in bpftool Makefile.
* Fix install target for bpftool: append DESTDIR to install path.

Create two targets to remove executable and documentation that would
have been previously installed with `make install` and `make
doc-install`.
Also create a "QUIET_UNINST" helper in tools/scripts/Makefile.include.
Do not attempt to remove directories /usr/local/sbin and
/usr/share/bash-completions/completions, even if they are empty, as
those specific directories probably already existed on the system before
we installed the program, and we do not wish to break other makefiles
that might assume their existence. Do remvoe /usr/local/share/man/man8
if empty however, as this directory does not seem to exist by default.
