b45a3b4162 toollib: Drop the bogus pv_read optimisation.
The toollib code for processing PVs given on commandline tried to be smart and
use pv_read, avoiding real metadata scanning. The premise of the optimisation
was that if there is an active MDA on the PV, it can be reliably used to
establish VG membership. This assumption is however wrong, since it's entirely
possible that this particular MDA is simply out of date, and the PV is not
actually in any VG. While this is a subtle and rare bug, it's still a bug. One
way to trigger it would be to hotplug an old disk which at some point was a PV
in an existing VG, having a seemingly valid MDA but with an old sequence
number. All commands that use normal scanning realize that this PV does not
belong into the VG anymore, but anything based on pv_read alone will believe it
does.

# SYNOPSIS
#
# AX_GCC_BUILTIN(BUILTIN)
#
# DESCRIPTION
#
# This macro checks if the compiler supports one of GCC's built-in
# functions; many other compilers also provide those same built-ins.
#
# The BUILTIN parameter is the name of the built-in function.
#
# If BUILTIN is supported define HAVE_<BUILTIN>. Keep in mind that since
# builtins usually start with two underscores they will be copied over
# into the HAVE_<BUILTIN> definition (e.g. HAVE___BUILTIN_EXPECT for
# __builtin_expect()).
#
# The macro caches its result in the ax_cv_have_<BUILTIN> variable (e.g.
# ax_cv_have___builtin_expect).
#
# The macro currently supports the following built-in functions:
#
# __builtin_assume_aligned
# __builtin_bswap16
# __builtin_bswap32
# __builtin_bswap64
# __builtin_choose_expr
# __builtin___clear_cache
# __builtin_clrsb
# __builtin_clrsbl
# __builtin_clrsbll
# __builtin_clz
# __builtin_clzl
# __builtin_clzll
# __builtin_complex
# __builtin_constant_p
# __builtin_ctz
# __builtin_ctzl
# __builtin_ctzll
# __builtin_expect
# __builtin_ffs
# __builtin_ffsl
# __builtin_ffsll
# __builtin_fpclassify
# __builtin_huge_val
# __builtin_huge_valf
# __builtin_huge_vall
# __builtin_inf
# __builtin_infd128
# __builtin_infd32
# __builtin_infd64
# __builtin_inff
# __builtin_infl
# __builtin_isinf_sign
# __builtin_nan
# __builtin_nand128
# __builtin_nand32

# __builtin_powi
# __builtin_powif
# __builtin_powil
# __builtin_prefetch
# __builtin_trap
# __builtin_types_compatible_p
# __builtin_unreachable
#
# Unsuppored built-ins will be tested with an empty parameter set and the
# result of the check might be wrong or meaningless so use with care.
