Subject: [meta-initramfs][PATCH V2 2/3] klibc.bbclass: Use forcevariable override to define flags
Precedence: list

This is required so it can override the CC settings when
clang is used because meta-clang uses toolchain-clang
override to set CC and friends so we need to use higher
order override, forcevariable is highest order.
