24a05ff503 allow collision tester to run in 32-bit mode 
though it's hardly useful,
but it allows CI to run runtime tests.

c11b0b96f8 fix #563 
ensure that building test tools preserves compilation flags
including -std=c99 and -std=c++11
when invoked with CFLAGS pre-set
so that it properly compiles with gcc <= 4.8 .

2c992d0cc7 merge xxh3 implementation within xxhash.h 
xxh3.h is no longer necessary
but remains available,
in case some programs do #include "xxh3.h" directly.

Also : bumped version number to v0.8.0

519dc67b23 Replace --std with -std, fix typo 
`--std` is improper but accepted. The correct option is `-std`.

4d4ce34a56 Fix Makefile portability issues 
Don't use `-mavx2 -maes` in collisions

It prevents `make test` from passing on non-x86 targets

TODO: proper Windows library flags: bfd accepts Linux flags, but
ld.lld errors on `-Wl,-soname`
