[OE-core] [PATCH] gcc-multilib-config: Ensure SDK_ARCH doesn't change target sigs

[Richard Purdie]

Changing SDKMACHINE (which changes SDK_ARCH) shouldn't cause
target task signatures to change. Exclude the dependency
on SDK_ARCH for this reason. It only affects nativesdk builds
and those already account for SDK_ARCH in the build WORKDIR paths.
