perf doc: Add support for KBUILD_BUILD_TIMESTAMP

When building man pages from a Git checkout, we consistently set the
man page date based on when the input was last changed. Otherwise, it
defaults to the build time, which is not reproducible.

Allow the date to be set through the KBUILD_BUILD_TIMESTAMP variable,
as for timestamps in the kernel itself.

perf doc: Define man page date when using asciidoctor

When building perf documentation with asciidoc, we use "git log" to
find the last commit date of each doc source and pass that to asciidoc
to use as the man page date.

When using asciidoctor, however, the current date is always used
instead. Defining perf_date like we do for asciidoc also doesn't
work because we're not using DocBook as an intermediate format.
The asciidoctor man page backend looks for the variable "docdate",
so set that instead.

perf Documentation: Support for asciidoctor

The asciidoc package seems behind the recent big wave of python3
conversion, and we were advised to switch to asciidoctor instead. It's
almost compatible but some extensions used for perf documentation don't
work with it. Here is the patch to cover them, and add the proper
support for asciidoctor.

Pass USE_ASCIIDOCTOR=yes to make for using asciidoctor instead of
asciidoc. The man source and manual attributes are passed via command
options. The support for these attributes have been fixed in the
latest asciidoctor code.

Since asciidoctor can covert to a man page and an HTML directly, we
can omit the dependency on xmlto when USE_ASCIIDOCTOR is set.

tools/perf: Fix double/triple-build of the feature detection logic during 'make install' et al

Linus reported the following perf build system bug:

'Another annoyance during that make was that "make install" seems to
want to re-make the thing I just built. That's absolutely horrible, [...]'

The thing that got re-built were 'only' the (numerous) feature checks,
not the whole project - but still it was mighty annoying as the feature
checks took 9+ seconds even on reasonably fast boxes.

Even with the autodep patches where feature detection is much faster
it wastes resources, wastes screen real estate and confuses users if
we execute feature detection twice.

There were two sources for these unnecessary re-builds of the feature
checks:

- Unnecessary nested invocations of $(MAKE), apparently to be able
to do conditional compilation dependent on documentation tools
presence. Use straight dependencies instead, with no nesting.

- A direct invocation of $(MAKE) to rebuild the PERF-VERSION-FILE.
This is apparently done to be able to include it into the
Makefile:

-include $(OUTPUT)PERF-VERSION-FILE

but that's entirely pointless for two reasons: 1) the version file
gets regenerated by the initial build pass anyway, 2) including it
is futile, given its contents:

#define PERF_VERSION "3.12.rc3.g8510c7"

'make' will interpret that as a comment line...

So just remove this part of the doc-generation logic.

With these things fixed a 'make install' now rebuilds only what is needed.

A repeated 'make install' on an already built tree is super fast now,
it finishes in under 0.3 seconds:

#
# After the patch:
#

$ time make install

...

real 0m0.280s
user 0m0.162s
sys 0m0.054s

Prior all the autodep changes and prior this fix, a repeat 'make install'
took 24.1 seconds (!) on the same system:

#
# Before the patches:
#

$ time make install

...

real 0m24.109s
user 0m21.171s
sys 0m2.449s

Which almost entirely was caused by fixable build system fat.
We are now literally ~86 times faster.

A fresh rebuild and install now takes just 11.4 seconds:

#
# After the patch:
#

$ make clean
$ time make -j16 install

...

real 0m11.457s
user 1m43.411s
sys 0m7.610s

Without the patches it took 27.8 seconds:

#
# Before the patches:
#

$ make clean
$ time make -j16 install

...

real 0m27.801s
user 1m59.242s
sys 0m9.749s

So even in the complete rebuild case we are now ~2.5 times faster.
