Doing a fresh install on a user home directory needs to first make sure
that the ~/libexec/perf-core/ directory is present so that
'perf-archive' like scripts, 'perf test' attr config files and 'perf
script' scripts can be installed.

Add a test for parsing a non-sample event when there is more than one
selected event but no sample_id_all bit set.
The test fails because of a bug in the evlist logic. That is fixed in a
separate patch.

perf_evlist__config() must be moved to a separate source file to avoid
Python link errors when adding support for PERF_SAMPLE_IDENTIFIER.
It is appropriate to do this because perf_evlist__config() is a helper
function for event recording. It is used by tools to apply recording
options to perf_evlist. It is not used by the Python API.

Plus variants with O= and DESTDIR set.
This patch fixes the above and was tested with the following:

$ make tools/perf

Adding automated test for breakpoint event signal handler checking if
it's executed properly.
The test is related to the proper handling of the RF EFLAGS bit on
x86_64, but it's generic for all archs.
First we check the signal handler is properly called and that the
following debug exception return to user space wouldn't trigger
recursive breakpoint.
This is related to x86_64 RF EFLAGS bit being managed in a wrong way.
Second we check that we can set breakpoint in signal handler, which is
not possible on x86_64 if the signal handler is executed with RF EFLAG
set.
This test is inpired by overflow tests done by Vince Weaver.

compatibility with older versions of bison.
This patch fixes this build error with older versions of bison.

continuing with the build instead of failing halfway, if either are
missing.
