Memory Sanitizer requires passing different options to CFLAGS and LDFLAGS: besides the mandatory -fsanitize=memory, one needs to pass header and library paths, and passing -L to a compilation step triggers -Wunused-command-line-argument. So introduce a separate variable for linker flags. Use $(SAN_CFLAGS) as a default in order to avoid complicating the ASan usage.
