LFS 7.3 Glibc-2.17 section 5.7 build error

This is my first time building LFS. I was able to solve the errors along the way, but I was clueless about this error.

The error message is
../sysdeps/ieee754/flt-32/s_isnanf.c:37:1: error: '__EI___isnanf' aliased to external symbol '__GI___isnanf'
make[2]: *** [/mnt/lfs/sources/glibc-build/math/s_isnanf.os] Error 1
make[2]: Leaving directory `/mnt/lfs/sources/glibc-2.17/math'
make[1]: *** [math/subdir_lib] Error 2
make[1]: Leaving directory `/mnt/lfs/sources/glibc-2.17'
make: *** [all] Error 2
The only thing I have done differently is running
ln -sv libgcc.a $($LFS_TGT-gcc -print-libgcc-file-name | sed 's/libgcc/&_eh/')
instead of
ln -sv libgcc.a `$LFS_TGT-gcc -print-libgcc-file-name | sed 's/libgcc/&_eh/'`
from the book.

There are also two warnning messages from configure
configure: WARNING: using cross tools not prefixed with host triplet
*** These auxiliary programs are missing or incompatible versions: autoconf
*** some features will be disabled.
*** Check the INSTALL file for required versions.
I have installed the autoconf on the host system and remove the build folder, build the Glibc again received the same warning and error message.

The result of version check is
bash, version 4.2.37(1)-release
/bin/sh -> /bin/bash
Binutils: (GNU Binutils for Ubuntu)
bison (GNU Bison) 2.5
/usr/bin/yacc -> /usr/bin/bison.yacc
bzip2, Version 1.0.6, 6-Sept-2010.
Coreutils: 8.13
diff (GNU diffutils) 3.2
find (GNU findutils) 4.4.2
GNU Awk 4.0.1
/usr/bin/awk -> /usr/bin/gawk
gcc (Ubuntu/Linaro 4.7.2-2ubuntu1) 4.7.2
(Ubuntu EGLIBC 2.15-0ubuntu20) 2.15
grep (GNU grep) 2.12
gzip 1.5
Linux version 3.5.0-17-generic (buildd@roseapple) (gcc version 4.7.2 (Ubuntu/Linaro 4.7.2-2ubuntu1) ) #28-Ubuntu SMP Tue Oct 9 19:32:08 UTC 2012
m4 (GNU M4) 1.4.16
GNU Make 3.81

GNU sed version 4.2.1

I have rebuilded binutil, gcc, and kernel API header all over again, but the problem remained. I will appreciate any insights and let me know if you need more information.

I've come across some references to this being a problem with the version of binutils installed try upgrading to binutils-2.23.1, also someone fixed it by reinstalling the linux headers.

You said you had fixed some other errors what were they? they may have a bearing on this problem.
