[Clfs-support] errors compiling eglibc 32 bit final

[Gerhard Erker Gmail1]

Hello,
I have the following computer:

lenovo Idea-centre K430, 8GB Memory, 2 TB HDD, nvidia GTX 650, Intel 
Core i5 processor
My hostsystem is Opensuse 13.1 64 bit with all updates made.

When compiling eglibc 32 bit final i got the following errors:

make[2]: *** [/sources/eglibc-build/posix/tst-getaddrinfo4.out] Error 1

Output of the corresponding file:
FAIL getaddrinfo(service=NULL, family=0, flags=0): No address associated 
with hostname: No such file or directory
FAIL getaddrinfo(service=NULL, family=0, flags=32): No address 
associated with hostname: No such file or directory

FAIL getaddrinfo(service=http, family=10, flags=0): Servname not

is this error critical? Can anyone say from where this error came ?

make[2]: [/sources/eglibc-build/posix/annexc.out] Error 1 (ignored)
make[1]: *** [posix/tests] Error 2

make[2]: *** [/sources/eglibc-build/debug/tst-backtrace6.out] Error 1

Once again: is this error critical for the build? Have I made any 
mistake when building tools or cross-tools?

Many thanks for your help.
