package/binutils: remove BR2_BINUTILS_ENABLE_LTO

Currently, this option doesn't do anything. It only adds
--enable-plugins --enable-lto to the configure flags, but doesn't
disable them if it is not set. Since both of these default to enabled,
plugins and lto are effectively always enabled.

There really is no need to make this configurable: it adds a bit of size
and build time to host-binutils, but we don't care about that for host
tools. It's still up to individual builds to enable the LTO options.

Therefore, remove the option entirely. For clarity, explicitly pass
--enable-plugins --enable-lto to configure.
