Nope. Unfortunately, whilst compiling the instrumenter is usually a no brainer 
on common distros, I have no clue wrt what your LFS setup is providing as libc 
headers, which seems to be at the root of the problem, since some of them are 
used to compile GCC against.

You could get rid of the C++ support if you don't plan to instrument C++ apps to 
run with the simulator, i.e.: in sim/gcic/GNUmakefile, just strip out "c++" from 
the LANG variable passed to the configure script, called from the 
gcc-build/.gcic-built rule. Just a work-around, but would perhaps allow you to 
build the simulator properly.
