Adhemerval Zanella b8386c2859 Remove PREPARE_VERSION and PREPARE_VERSION_KNOW 
This patch removes the PREPARE_VERSION and PREPARE_VERSION_KNOW macro
and uses a static inline function instead, get_vdso_symbol.  Each
architecture that supports vDSO must define the Linux version and its
hash for symbol resolution (VDSO_NAME and VDSO_HASH macro respectively).

It also organizes the HAVE_*_VSYSCALL for mips, powerpc, and s390 to
define them on a common header.

The idea is to require less code to configure and enable vDSO support
for newer ports.  No semantic changes are expected.

Checked with a build against all affected architectures.

	* sysdeps/unix/make-syscalls.sh: Make vDSO call use get_vdso_symbol.
	* sysdeps/unix/sysv/linux/aarch64/gettimeofday.c (__gettimeofday):
	Use get_vdso_symbol instead of _dl_vdso_vsym.
	* sysdeps/unix/sysv/linux/powerpc/time.c (time): Likewise.
