The previous patch added the function 'CT_DoMultilibTarget()' to scripts/build/arch/*.sh. This patch calls the common function to (currently) get just the target tuple for the current multilib target. This patch was originally by: Cody P Schafer Changed by Alexey Neyman: first, try `gcc -print-multiarch`. If it is supported, use whatever it reports. Otherwise, fall back to our guesswork. Move "i486" quirk into glibc.sh, as it is specific to glibc (e.g. uclibc will need i386, which is what GCC reports).
