Subject: [PATCH] lib/macro/internal: Only use alloc instead of std

Fix #47. The problem is that for stable compilers older than 1.51, we used to
support no-std alloc environments, but not no-alloc environments. For compilers
1.51 and later, we additionally support no-alloc environments using resolver =
"2" in Cargo.toml of the end binary.
