Add CXXFLAGS to ALL_LDFLAGS ( #1178 )
...
pzstd requires C++11, which older C++ standard libraries like libstdc++
as used on OS X 10.8 and earlier don't support. The user might address
this by setting "CXXFLAGS=-stdlib=libc++". This flag must be used both
at compile time and at link time. Asking the user to also put the flag
in LDFLAGS is undesirable because then the flag would also be used when
linking C code, which would be inappropriate.

Make the build reproducible
...
Whilst working on the Reproducible Builds effort [0], we noticed
that zstd could not be built reproducibly.
This is due to the manual page encoding the number of CPUs from the
build machine and thus varies across builds.
This was originally filed in Debian as #897904 [1].

It can have other effects, such as pulling in extra libraries. Without it,
riscv build fails with undefined reference to `__atomic_compare_exchange_1'.
