arm/trusted-firmware-a: don't set LD if LTO is enabled

Browse Source 
Some platforms (like Allwinner A64/sun50i_a64) have LTO enabled
in the Makefiles, which causes a linking error when using ld:

| [...]/aarch64-oe-linux/aarch64-oe-linux-ld: -f may not be used without -shared

Add an option to be able to indicate in the recipe if the plaform has LTO enabled,
and only pass LD to make in case LTO is disabled, otherwise let it use $CC (as set by the Makefile).

The option is disabled by default to keep the existing behavior.
