This PR fixes the build on Android and RHEL7 by defining LINUX_NO_EXPLICIT_BZERO when
explicit_bzero
is unavailable. It turns out there was already an autoconf check for this function, so I reused it.Instead of creating a new Makefile variable, I appended the definition to LIBHACL_CFLAGS. This may be useful if HACL uses it in other files in the future.
