bpo-42087: Remove support for AIX 5.3 and below (GH-22830)
As AIX 5.3 and below do not support thread_cputime, it was decided in
https://bugs.python.org/issue40680 to require AIX 6.1 and above. This
commit removes workarounds for — and references to — older, unsupported
AIX versions.

# FILE: makexp_aix
# TYPE: standalone executable
# SYSTEM: AIX
#
# DESCRIPTION: This script creates an export list of ALL global symbols
# from a list of object or archive files.
#
# USAGE: makexp_aix <OutputFile> "<FirstLine>" <InputFile> ...
#
# where:
# <OutputFile> is the target export list filename.
# <FirstLine> is the path/file string to be appended
# after the "#!" symbols in the first line of the
# export file. Passing "" means deferred resolution.
# <InputFile> is an object (.o) or an archive file (.a).
#
# HISTORY:
# 3-Apr-1998 -- remove C++ entries of the form Class::method
# Vladimir Marangozov
#
# 1-Jul-1996 -- added header information
# Vladimir Marangozov
#
# 28-Jun-1996 -- initial code

# Extract the symbol list using 'nm'
# Here are some hidden tricks:
# - Use the -B flag to have a standard BSD representation
# of the symbol list.
# - Use the -x flag to have a hex representation of the symbol
# values. This fills the leading whitespaces, thus simplifying
# the sed statement.
# - Eliminate all entries except those with either "B", "D"
# or "T" key letters. We are interested only in the global
# (extern) BSS, DATA and TEXT symbols. With the same statement
# we eliminate object member lines relevant to AIX 4.
# - Eliminate entries containing a dot. We can have a dot only
# as a symbol prefix, but such symbols are undefined externs.
# - Eliminate everything including the key letter, so that we're
# left with just the symbol name.
# - Eliminate all entries containing two colons, like Class::method
