[gentoo-user] glibc problem with amd64

I tried to compile openv (Intel's computer vision library) on amd64 (64 bit mode) and it failed  with the gollowing message:

 I would like to note that:
  * The cmpilation went smoothly on a P4 (32 bit) with the same glibc (2.3.5-r2)
  * I saw several post on this glibc issue with other distros. One suggested to compile glibc with -funit-at-a-time.  but this option aborted glibc compilation.
 
 Any idea?

AFAIK the build should not be calling out crti.o, crtbeginS.o, and
crtendS.o directly.  These are added by gcc automatically.  Maybe the
-nostdlib flag can help here...

CFLAGS=-nostdlib emerge ...

Still can not compile opencv:
 1. Tried with CFLAGS="-O2 -march=k8 -pipe" as recommended in "Gentoo Linux/AMD64 FAQ". The compilation fails at the same point.
 2. (Richard Fish): The links to crti.o and crtbeginS.o are in the glibc, they are not in the opencv makefile.
 
 Any more Ideas?
 Should it be addressed to the gentoo developers ?
