Jouni Malinen d438b4a3ce tests: Fix CFLAGS passing for new fuzzing tools
src/*/Makefile needs to allow additional CFLAGS values to be provided
from the calling Makefiles so that the clang command line arguments to
enable sanitizers consistently. In addition, it can be useful to be able
to provide CC, CFLAGS, and LDFLAGS from external setup while still
requesing LIBFUZZER=y build. Allow that by not overriding these
variables if they are already set.

hostap.git fuzz testing
-----------------------

These tools can be used for fuzz testing of various components used
within wpa_supplicant and hostapd. Each directory contains a fuzzing
tool that focuses on one input handler. Each tool can be compiled either
to work with the libFuzzer or as a separate tool that reads the input
from a file specified on the command line, e.g., for American fuzzy lop
(afl-fuzz). Example test corpus is included in */corpus directory.

Example fuzzing with libFuzzer

cd @TOOL@
make clean
make LIBFUZZER=y
./@TOOL@ corpus

Example fuzzing with afl-fuzz

cd @TOOL@
make clean
CC=afl-gcc make
afl-fuzz -i corpus -o findings -- $PWD/@TOOL@ @@
