S390: Clean setjmp, longjmp, getcontext symbols.
For each function setjmp, longjmp, getcontext, there exist a symbol <func> and a default/versioned symbol <func>@@GLIBC_2.x in the build obj-files. This is wrong because it should only exist an unversioned or a default-versioned symbol with the same name in an obj-file. Glibc can't be build with recent binutils. See the already fixed linker bug https://sourceware.org/bugzilla/show_bug.cgi?id=19073. Nevertheless, this patch cleans this up. Furthermore the BSD entry points setjmp, _setjmp were marked as weak, but should be strong as on other architectures. (see https://sourceware.org/ml/libc-alpha/2014-07/msg00568.html for an older discussion with Andreas Schwab) Some whitespace issues are corrected in sysdeps/s390/s390-64/setjmp.S, too. But there is no change in the assembler code. ChangeLog: * sysdeps/s390/longjmp.c (longjmp, _longjmp, siglongjmp): Don't create weak aliases, because versioned symbols are created later. * sysdeps/s390/s390-32/setjmp.S (setjmp, _setjmp): Remove weak and rename to an unique name in SHARED case due to existing versioned symbols. * sysdeps/s390/s390-64/setjmp.S: Likewise. * sysdeps/unix/sysv/linux/s390/s390-32/getcontext.S (getcontext): Create weak alias only in non SHARED case. * sysdeps/unix/sysv/linux/s390/s390-64/getcontext.S: Likewise.
