c2c0c47d5f fix NULL ptr arithmetic of lz4:1572 
was blindly adding an offset (0) to `dictionary` which could be `NULL`.

0d2570b7c5 Add CC propagation to 'make usan' 
The following command doesn't work as intended

```
cd
git clone https://github.com/lz4/lz4.git
cd lz4
make usan MOREFLAGS='-Wcomma -Werror'
```

```
Cleaning completed
cc: error: unrecognized command line option ‘-Wcomma’; did you mean ‘-Wcomment’?
make[3]: *** [<builtin>: ../lib/lz4.o] Error 1
make[2]: *** [Makefile:65: lz4] Error 2
make[1]: *** [Makefile:133: test] Error 2
make: *** [Makefile:158: usan] Error 2
```

Because the following part of the `Makefile` doesn't propagate `CC`, `CFLAGS` and `LDFLAGS` to child `$(MAKE)` properly.

```
.PHONY: usan
usan: CC      = clang
usan: CFLAGS  = -O3 -g -fsanitize=undefined -fno-sanitize-recover=undefined -fsanitize-recover=pointer-overflow
usan: LDFLAGS = $(CFLAGS)
usan: clean
        $(MAKE) test FUZZER_TIME="-T30s" NB_LOOPS=-i1
```

We need explicit propagation for child process

```
-       $(MAKE) test FUZZER_TIME="-T30s" NB_LOOPS=-i1
+       CC=$(CC) CFLAGS=$(CFLAGS) LDFLAGS=$(LDFLAGS) $(MAKE) test FUZZER_TIME="-T30s" NB_LOOPS=-i1
```

After that, `make usan` works and it shows expected runtime error.

```
$ make usan MOREFLAGS='-Wcomma -Werror'

```

Please note that `make usan` is working at travis-ci.  Because `.travis.yml` has the following [explicit `compiler:` setting](7a966c1511/.travis.yml (L66)).

```
    - name: (Trusty) USan test
      dist: trusty
      compiler: clang
      script:
        - make usan MOREFLAGS=-Wcomma -Werror
```
