    cross.bbclass: Remove usage of host flags for cross-compilation
    
    BUILD_* flags can't be used as TARGET_* flags even for "cross" packages.
    
    gcc-cross buils leaks config.log's through "gcc-stashed-builddir" and
    TARGET_* flags to libgcc cross-build through "gcc/libgcc.mvars" file
    on "gcc-stashed-builddir". This means that if BUILD_CFLAGS contains
    host-specific flags like "-isystem/usr/include" libgcc build will
    fail "do_qa_configure" and "do_package_qa" checks.
    
    Remove host-related flags from TARGET_* flags for gcc-cross build.
