2b1d5df1f2 linux/perf: forcefully disable the features with missing dependencies
Forcefully disable the features that have optional dependencies that are
not enabled in Buildroot.

Disable support for bionic since, well, we're not Android.

Slightly re-order the variables to have semantically-related variables
together, with features last.

d4a2020424 linux/perf: honour the number of parallel jobs
perf does not honour the -j flags we pass to make; it yet again tries to
reinvent the wheel and by default uses the number of CPUs as the number
of parallel jobs.

Fortunately, in their infinite wisdom, the insane developpers of the
perf buildsystem were kind enough to provide us with a variable we can
set to specify the number of parallel jobs.

c306e0493a linux/perf: really do not build the documentation
The perf buildsystem, inside the kernel, is not really amenable to be
easily used...

Regarding the documentation, it will forcefully try to detect asciidoc
and, with the latest versions, xmlto, completely disregarding what the
user may provide.

We currently pass ASCIIDOC= (the empty string) on the make command line,
as an attempt to disable building the documentation, but that has no
effect whatsoever on perf: that variable is not passed down to the
sub-sub-make (yes, a two-level depth) that is responsible for building
the documentation.

We really do not want to build any of the documentation (the user can
refer to the documentation on his own development machine), so we use a
little dirty trick: we provide a GNUmakefile beside the existing
Makefile for the documentation; GNUmakefile always takes precedence over
a Makefile when both are present. We only provide a catch-all-no-recipe
rule in that GNUmakefile, so it really does nothing useful, except avoid
building the documentation.

7f3a52f981 perf: append endianness argument to ld when building for MIPS
We need to pass an argument to ld for setting the endianness when
building it for MIPS architecture, otherwise the default one will always
be used (which is big endian) and the compilation for little endian will
always fail showing an error like this one:

LD    foo.o
mips-linux-gnu-ld: foo.o: compiled for a little endian system and target
is big endian

77e7cdb5de perf: remove tests from target
The perf tool installed test files in
    output/target/usr/libexec/perf-core/tests/
which amounted to about 30+K.

Since they are not needed for normal perf operation, remove them.

1326e76185 package/perf: migrate perf to use the new linux-tools infrastructure
Remove the perf package and add legacy handling.

[Thomas:
  - improve the Config.in.legacy help text
  - improve the comment explaining why we pass O= when building perf]
