Which version of LFS are you building?
I see there went something wrong compiling and installing GCC pass 2.
what do you get if you type ./gcc -v
Did you do the sanity checks and applied all the patches?
The sanity check from GCC pass 2
At this point it is strongly recommended to repeat the sanity check we performed earlier in this chapter. Refer back to Section 5.7, “Adjusting the Toolchain,” and repeat the test compilation. If the result is wrong, the most likely reason is that the GCC Specs patch was not properly applied.
If gcc -v didn't work you have to do the gcc pass 2 again.
