Hi,

i get a build-failure on s390 due to the latest change in 
nptl/pt-longjmp.c 
(https://sourceware.org/ml/libc-alpha/2015-02/msg00123.html).
The s390-version of pt-longjmp.c includes the generic one and adds an 
additional compat-version, because those symbols were introduced and 
reverted in glibc 2.19.

This patch fixes the inclusion of nptl/pt-longjmp.c and uses the 
introduced macro DEFINE_LONGJMP to generate the additional symbol for 
the compat-version.

Ok to commit?

Bye
Stefan

	* sysdeps/unix/sysv/linux/s390/pt-longjmp.c
	(__v1longjmp): Remove versioned symbol.
	(__v1siglongjmp): Remove alias and versioned symbol.
	(__v2longjmp): Use DEFINE_LONGJMP instead of alias.
	(__v2siglongjmp): Likewise.

Drop the SHARED condition.  SHLIB_COMPAT already covers that.

Otherwise this looks fine to me.
