-Subject: [PATCH] Augment, rather than replace, existing RUSTFLAGS when
- building
-
-Some complex environments, like Void's cross-compilation environment,
-use RUSTFLAGS to control the behavior of rust compilation. Rather than
-overwriting RUSTFLAGS with custom flags, augment any existing RUSTFLAGS
-to preserve these environments.
