Verification error with glibc 2.2.5

Dear Developers.

I have been trying to compile glibc 2.2.5 on my Linux box, but 
a few tests fail :-( 

The failling tests are:
  math 
  make[2]: *** [/mnt/disk3/glibc_build/math/test-float.out] Error 1
  make[2]: *** [/mnt/disk3/glibc_build/math/test-ldouble.out] Error 1
  make[2]: *** [/mnt/disk3/glibc_build/math/test-ildoubl.out] Error 1
  make[2]: *** [/mnt/disk3/glibc_build/math/test-ifloat.out] Error 1

  dlfcn
  make[2]: *** [/mnt/disk3/glibc_build/dlfcn/tstcxaatexit.out] Error 139
  make[2]: *** [/mnt/disk3/glibc_build/dlfcn/tstatexit.out] Error 139

The files are attached.

Here's a little about my CPU:
  XXIII:[49]0:~/download>cat /proc/cpuinfo 
  processor       : 0
  vendor_id       : AuthenticAMD
  cpu family      : 5

  bogomips        : 999.42

And my gcc:
  XXIII:[50]0:~/download>gcc --version
  gcc (GCC) 3.1

Unfortunately I don't have much more to go on, but I still hope the 
information is usefull.
