commit 65402b410d9c0f3b85749a6d771d27f783026da1
Author: Andrew Senkevich <andrew.senkevich@intel.com>

Better workaround for aliases of *_finite symbols in vector math library.
Old workaround based on assembly aliases can lead to link fail (bug 19058).
This patch makes workaround in another way to avoid it.
[BZ #19058]
* math/Makefile ($(inst_libdir)/libm.so): Added libmvec_nonshared.a
to AS_NEEDED.
* sysdeps/x86/fpu/bits/math-vector.h: Removed code with old workaround.
* sysdeps/x86_64/fpu/Makefile (libmvec-support,
libmvec-static-only-routines): Added new file.
* sysdeps/x86_64/fpu/svml_finite_alias.S: New file.
* NEWS: Mention this fix.
(cherry picked from commit 060f8dbd0ca6eb17d20442dc4df72c2a707bdf86)
