gcc-configure: Pass distinct target flags

When building gcc-cross-canadian libgcc is built using
headers from gcc-crosssdk and not the target sysroot
because we do not pass proper CFLAGS for target bits
so it ends up using CFLAGS that were meant for compiling
canadian gcc itself. It does not show up as a problem
when building SDK with eglibc because eglibc-nativesdk
and eglibc have identical headers. The problem shows
up clearly when you try to build uclibc based meta-toolchain
since then nativesdk libc and target libc are different
