Use %ifdef in sysdeps/unix/sysv/linux/powerpc/powerpc64/shlib-versions.

This patch makes
sysdeps/unix/sysv/linux/powerpc/powerpc64/shlib-versions use %ifdef
conditionals around the different symbol version definitions for big
and little endian.  (It doesn't actually change the host patterns used
for those definitions; the point is to make it possible to remove the
first column from shlib-versions by eliminating the last case where it
would be harmful for it to be treated as .*-.*-.*.)  The conditional
is based on the ELFv1/ELFv2 distinction rather than BE/LE, since
that's what's already tested in configure and used for the ld.so
soname in the Makefiles.  (Of course if BE ELFv2 were supported in
future, it would get new symbol versions and so need new
conditionals.)

	* sysdeps/unix/sysv/linux/powerpc/powerpc64/configure.ac
	(HAVE_ELFV2_ABI): AC_DEFINE in ELFv2 case.
	* sysdeps/unix/sysv/linux/powerpc/powerpc64/configure:
	Regenerated.
	* config.h.in (HAVE_ELFV2_ABI): New macro undefine.
	* sysdeps/unix/sysv/linux/powerpc/powerpc64/shlib-versions:
	Condition symbol version definitions on [HAVE_ELFV2_ABI].
