arch,toolchain,xcompile: Use the compiler fronted as a linker

Code generation when using LTO is not done until after linking, so the
compiler must be invoked at all linking stages instead of the linker.
Replace $(LD) with $(CC), and prefix all linker-specific flags with -Wl
and replace the spaces by commas so they will be passed to the linker.

Test: Pass -m32 to compiler frontend
