#-------------
the problem is glibc. And  I may have tracked down its source.  It is in the 
clfs build.  I decided to rebuild clfs and I reached elibc-2.12 specifically 
this page:-

http://cross-lfs.org/view/svn/x86_64-64/final-system/eglibc.html

AND I have done  this :

cp -v ../eglibc-2.12/iconvdata/gconv-modules iconvdata
make -k check >eglibc-check-log 2>&1 ; grep Error eglibc-check-log

and this is the result:-

`../eglibc-2.12/iconvdata/gconv-modules' -> `iconvdata/gconv-modules'
make[2]: [~/eglibc-build/posix/annexc.out] Error 1 (ignored)
make[2]: *** [~/eglibc-build/rt/tst-cputimer1.out] Error 1
make[1]: *** [rt/tests] Error 2
make: *** [check] Error 2


advice would be appreciated

sincerely
