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
