Hi,

according to the -Wundef flag, i got a warning on S390 for 
__PTHREAD_MUTEX_HAVE_ELISION.
In combination with the -Werror flag for nptl/tst-initializers1* 
testcases, the prerequirements for make check fails because of 
build-errors and no tests.sum is generated.
For S/390 lock elision is currently not available.

Bye
