[2.26 COMMITTED] posix: Fix compat glob code on s390 and alpha

[Florian Weimer]

From: Adhemerval Zanella <adhemerval.zanella@linaro.org>

This patch fixes the compat glob implementation consolidation from
commit 116f1c64d with the following changes:

  - Add a compat implementation on s390 to avoid the architecture
    to build the symbols on default linux oldglob.c by setting
    GLOB_NO_OLD_VERSION.

  - Remove the duplicate rule to build oldglob on alpha.

Checked on s390-linux-gnu and alpha-linux-gnu using build-many-glibc.py.

	* sysdeps/unix/sysv/linux/s390/s390-32/oldglob.c: New file.
	* sysdeps/unix/sysv/linux/alpha/Makefile
	[$(subdir) = csu] (sysdep_routines): Remove rule.

(cherry picked from commit 3ca622e4d6054c0b99b2df36580462663edc8d12)
