All C compiler warnings are disabled are disabled by -w. This change
removes the -w from flex and bison targets. To avoid implicit
declarations header files are declared as targets and included.

Tested with GCC 9.3.0 and clang 9.0.1.

v2. predicates disabling the warnings on more recent bison and flex
    versions (3.5.3 and 2.6.4 respectively). An alternative would be
    to disabled a large number of warnings to cover the warnings
    generated in older distributions:
  flex_flags := -Wno-switch-enum -Wno-switch-default -Wno-unused-function \
    -Wno-redundant-decls -Wno-sign-compare -Wno-unused-parameter \
    -Wno-missing-prototypes -Wno-misleading-indentation
  bison_flags := -DYYENABLE_NLS=0 -Wno-unused-parameter -Wno-nested-externs \
    -Wno-implicit-function-declaration -Wno-switch-enum

Previously posted as a single change:

Allow pmu parser to be debugged as the parse-events and expr currently are.
Enabling this requires the C code to set perf_pmu_debug.

Declare flex header file output so that bison C files can depend upon
them. As there are multiple output targets $@ is replaced by the target
name.

Rather than disable all warnings with -w, disable specific warnings.
Predicate enabling the warnings on more recent flex versions.
Tested with GCC 9.3.0 and clang 9.0.1.

Rather than disable all warnings with -w, disable specific warnings.
Predicate enabling the warnings on a recent version of bison.
Tested with GCC 9.3.0 and clang 9.0.1.

So for the parts that you kept unchanged since Jiri acked it, please
next time collect that Acked-by, ok?

Going thru this now.

So, it is failing with older versions of alpine Linux, but then at
alpine 3.8 I noticed that the problem is happening only when building
with this following set of options, and when building with gcc, building
with clang, i.e. adding CC=clang to the following make command line
works.

+ make 'ARCH=' 'CROSS_COMPILE=' 'EXTRA_CFLAGS=' 'LIBCLANGLLVM=1' -C /git/linux/tools/perf 'O=/tmp/build/perf'

I'll also check if this isn't because these container tests do multiple
make calls, with different sets of options (NO_LIBBPF=1, another with
NO_LIBELF=1, the one with LIBCLANGLLVM=1, etc) and perhaps the stuff
from previous builds pollute a subsequent build, i.e. will try adding a
rm -rf to the O= directory if missing.
