No, because this will only work for internal toolchains. So instead,
you need to put this dependency in two places:
1/ In package/musl/musl.mk, where it should be an unconditional
dependency.
2/ In toolchain/toolchain-external/toolchain-external.mk, where it
should be conditional on BR2_TOOLCHAIN_USES_MUSL.

Is it really a problem if it is processed before?
