[Clfs-support] eglibc and atlas problem on c{b}lfs

[bv]

Greetings,

I seem to have run up against linker problems on a newly minted cblfs setup 
regarding  latter versions of atlas3.9.3x.  
Th cblfs setup is derived from a new clfs build.

My setup has these
--amd64 cpu (2 cores) kernel-2.6.35.7
--gcc-4.5.2(with gfortran), eglibc-2.12.2 atlas3.9.3{3,9}

I compiled   the said versions of atlas on a setup with 
gcc-4.4.2/eglibc-2.10.1  many times.  Bit for the new setup I only obtain 
partial builds.  I found  this in the   build logs:-

From -(C) above there seems to be a problem with the linker.  but I only 
noticed this  with building atlas.

#-----------------------
this line 
function `_start':
/sources-28810/eglibc-2.12/csu/../sysdeps/x86_64/elf/start.S:109: undefined 
reference to `main'

referes to the the source tree of glibc  which was built in a dedicated  
directory out of the source tree.
#---------------------------------------

I would  be  grateful for   advice.

sincerely
