+Subject: [PATCH] cargo-build.sh: inherit $RUSTFLAGS
+
+When a packaging system like rpm invokes "meson build" in meson 0.64.0
+or later, it can use buildtype "plain" to control compiler flags itself
+via the CFLAGS, CXXFLAGS, and, in our case, RUSTFLAGS environment
+variables.
+
+Don't clobber RUSTFLAGS in src/cargo-build.sh. Simply append our own
+options to RUSTFLAGS. That way src/cargo-build.sh still controls
+compiler options when necessary, but inherits them from the build
+environment (especially in the buildtype "plain" case).
+
+See https://bugzilla.redhat.com/show_bug.cgi?id=2124697#c67 for Fedora
+packaging discussion around this topic.
