 Ah ha!  You are using the host's compiler in pass 2.  Wrong path,
failed to correctly specify a variable, omitting +h, or something

 The first pass of gcc builds a pseudo cross-compiler, hence the LFS
setting : just enough of a name change to fool the build system into
using the cross-compile routines (for separation from the host).
This compiler only supports 'C'.

 The second pass uses the 'cross' compiler to build a native C and
C++ compiler.

das eine Mal als Tragödie, das andere Mal als Farce
