Subject: classes/rust: remove unused variables
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=6a5a31690508483498e09eb286ca7147130e5852;p=thirdparty%2Fopenembedded%2Fopenembedded-core.git

classes/rust: remove unused variables

RUSTC_ARCHFLAGS is never passed anywhere, remove it.

RUSTC_BUILD_LDFLAGS is commented out, remove it.

HOST_CFLAGS et al are assigned to the CFLAGS for convenience, but are
not used anywhere and the same values are exported in cargo_common's
oe_cargo_fix_env().
