Accordingly gcc output on bigboy shows -msse4.1 where littleboy shows -mno-sse4.1. There are a few other differences, mainly in cache size (bigboy has l1=32 and l2=3072 where little boy has 64 and 1024 respectively. And gcc shows -mtune=core2 for bigboy where littleboy has -mtune=generic. There was no difference in output between littleboy's /tools/bin/gcc and /usr/bin/gcc, although the former was imported and the latter was built locally. Both had the -mno-sse4.1 flag. That surprised me. The linked libraries you requested are mpc, mpfr, gmp, dl, z, stdc++, m, gcc_s and libc (plus linux-vdso and ld-linux of course). The reason I am plugging this is that the book says you can reuse the chapter 5 toolkit to build additional LFS systems provided that you save it before carrying out the adjustments in section 6.10. There's nothing to suggest that doing this on a different computer would cause problems. -- If any members of GCHQ are reading this, shame on you!
