Fix multiarch DISTRO_FEATURE

Make get_gcc_multiarch_setting more elegant. Use a dictionnary
to store the config options and replace bb.data.getVar with d.getVar.
Remove i686 from the architecture list because it doesn't seem
to be a valid TARGET_ARCH any more in OE.
Configure gdb (gdb and gdb-cross) with --enable-64-bit-bfd if
multiarch DISTRO_FEATURE is present
