Glibc 2.7 tests include checks for atexit-like problems, i.e. call g++ or
link with libstdc++, which not build yet on this stage.

  cd $LFS_BUILD/glibc-2.7;
  sed -i -e 's/ tst-cancel24//' -e '/LDFLAGS-tst-cancel24 = -lstdc++/ d' nptl/Makefile
  sed -i -e 's/bug-atexit3 //' -e 's/ bug-atexit3-lib//' dlfcn/Makefile
  sed -i -e 's/tst-chk4 tst-chk5 tst-chk6 tst-lfschk4 tst-lfschk5 tst-lfschk6//' debug/Makefile

(before configure) will remove this tests and make 'make check' a bit happier.

Bests,
