# NOTE: we have to hardcode a fake UNAME otherwise it will build file extensions
# based on our host OS, not the target OS.  Also, zstd always builds both shared
# and static libraries so we must pass CFLAGS and LDFLAGS via environment variables.
# If we don't, the makefile can't append recipe-specific flags to them and it'll
# fail trying to build a static and shared library using the same flags.
# See: https://github.com/facebook/zstd/issues/3190
