You may be right, but do not forget that gcc-pass1 is built as a cross compiler, but used as a native compiler (for binutils and gcc passes 2). This is pretty non standard and undocumented, although it has been working since 2007 (on diy-linux, then imported to LFS), so the doc may not apply too...
