When configuring GNU GCC as the C compiler, we usually use the GNU BFD linker directly to link by default. However, this complicates things because we also need to support LTO, which can only be done when linking is done via the C compiler, and we cannot change the linker later on if some other part of the build system wants to enable LTO. This change migrates the default choice of linker to GCC if the C compiler is GCC, in order to enable this use-case. This should have no impact on anything outside of the build system, as by default GCC merely acts as a wrapper around BFD.
