I feel like we enable STATIC for aarch64-binutils to reduce package build times when using qemu-user. If we are building aarch64 packages natively, then perhaps we can turn that off in devel/binutils and enable LTO for aarch64-gcc?

Fixed this by enabling LTO in the aarch64-gcc packages instead in D25783.
