6.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Russell Currey <ruscur@xxxxxxxxxx>
[ Upstream commit dee3a6b819c96fc8b1907577f585fd66f5c0fefe ]
rust_is_available.sh uses cc-version.sh to identify which C compiler is
in use, as scripts/Kconfig.include does. cc-version.sh isn't designed to
be able to handle multiple arguments in one variable, i.e. "ccache clang".
Its invocation in rust_is_available.sh quotes "$CC", which makes
$1 == "ccache clang" instead of the intended $1 == ccache & $2 == clang.
cc-version.sh could also be changed to handle having "ccache clang" as one
argument, but it only has the one consumer upstream, making it simpler to
fix the caller here.
