Subject: [PATCH] For additional compatibility this adds REDIS_CFLAGS and
 REDIS_LDFLAGS support to MAKEFILE (#66)

This resolves (1.viii) from
https://github.com/valkey-io/valkey/issues/43
> REDIS_FLAGS will be updated to SERVER_FLAGS. Maybe we should also
allow REDIS_FLAGS -> SERVER_FLAGS as well, for an extra layer of
compatibility.
