Commit 6b491a86b7 ("perf build: Install libbpf headers locally when
building") installed copies of the libbpf headers into the build tree,
causing unnecessary noise from 'git status' after a perf tools build.
Add the 'libbpf/' subdirectory to the .gitignore file to silence it all
again.

Add support for decoding instructions for Intel Processor Trace. The
kernel x86 instruction decoder is copied for this.
This essentially provides intel_pt_get_insn() which takes a binary
buffer, uses the kernel's x86 instruction decoder to get details of the
instruction and then categorizes it for consumption by an Intel PT
decoder.

Decoding an Intel PT trace of the kernel requires an accurate kernel
object image. This is provided by making a copy of kcore. However the
copy needs to be made under the same conditions as the original
recording, and then it needs to be associated with the perf.data file.
The perf-with-kcore script does that.
The script also checks the permissions on the buildid cache and can be
used to fix them. That is needed for distributions where root does not
have a home directory and consequently writes to the same buildid cache
as the user, resulting in cached files that the user does not have
access to.
Example:
$ ./perf-with-kcore
Usage: perf-with-kcore <perf sub-command> <perf.data directory> [<sub-command options> [ -- <workload>]]
<perf sub-command> can be record, script, report or inject
or: perf-with-kcore fix_buildid_cache_permissions
$ ./perf-with-kcore record pt_uname -e intel_pt// -- uname

This commit squashes several commits that remove:
unnecessary uname calls
`sh -c'
BUILT_INS and QUIET_BUILT_IN
They have no effect, and the `fixup-builtins' and `check-builtins.sh'
scripts don't even exist.
RUNTIME_PREFIX
It's currently never anything but unset, and it's apparently
only meaningful when Microsoft Windows is the operating system
(according to the source for git).
TEST_PROGRAMS
EXTRA_PROGRAMS
unused SHELL_PATH_SQ portions
unused test for V=2
useless exports
Only when `V' is undefined (that is, only when the value of `V'
is empty) is `export V' performed, which just has the effect of
placing the empty-valued variable `V' in the environment.
The only other script to make use of `V' is `Documentation/Makefile',
which only checks whether `V' is undefined (that is, whether the value
of `V' is empty); hence, the `export V' has no effect whatsoever.
Similarly, `export QUIET_GEN' is useless because it will only have
a non-empty value when `V' has an empty-value, and when `V' has
an empty-value, `QUIET_GEN' is always explicitly set in every
script in which it is used.
`DESTDIR' is only ever defined by the user via the environment
or the command line, both of which are automatically exported
to sub-make processes. Furthermore, no non-make sub-scripts
make use of `DESTDIR' as an environment variable.
No other scripts use `perfexec_instdir'.
unused QUIET_SUBDIR{0,1}
TAR and RPMBUILD
PTHREAD_LIBS
Maintainer's dist rules and commands
distclean target
Test suite coverage testing
PRINT_DIR and NO_SUBDIR
`configure' target
NO_CURL
@@PERF_VERSION@@ substitution
Without the sed command, all of the rule's commands can be reduced
to a single line that copies a file and sets the permissions properly
in the process.
`make test' echo line
template_instdir
PERF-BUILD-OPTIONS
double-colon rules
The use of double-colon rules seems misguided or vestigial git.
Essentially hard-coded $(SCRIPTS) expansion
