Commit 34ccadcd3334 ("ARM: don't use --gc-sections with LTO when using
private libgcc") left out --gc-sections for LTO builds that use the
private libgcc. Since commit a55014d09b29 ("Makefile: Allow LTO to be
disabled for a build"), the condition tests LTO_ENABLE, which the top
Makefile sets only after it has read arch/arm/config.mk, so U-Boot
proper has been linked with --gc-sections ever since.Once the next patch sets LTO_ENABLE in time, the condition would take effect again. U-Boot proper would then keep the sections that nothing uses, such as the .discard.addressable section of keep-syms-lto.o. Keep --gc-sections for all builds. This changes no image on main.
