Add fPIC

We can probably add some debug printing code here at some point to try
and bring bugs upstream, if it makes sense.

+# argp-standalone
+
+This is a continuation of [Niels Möller](https://www.lysator.liu.se/~nisse/)'s
+work on an argp library for systems which don't provide one themselves (most
+non-GNU ones).
+
+After noticing issues with executables built against argp-standalone 1.3, I
+decided to fork it and continue the effort.
+
+This repository is the result of making a timeline with releases 1.0 to 1.3
+(obtained from [here](https://www.lysator.liu.se/~nisse/misc/)) of the original
+argp-standalone, copying files from glibc 2.33 and fixing them up for
+compatibility, and finally some general clean up. I commited many trivial
+changes from the glibc version in order to make updating easier.
+
+It is my expectation that this library will be useful to others. Feel free to
+open an issue or make a PR.
+
+## License
+
+Since this repository is based on GNU C Library source code and changes from
+Niels and collaborators, it is licensed primarily under the GNU Lesser General
+Public License, version 2.1 or later (SPDX: `LGPL-2.1-or-later`).

-# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
-# $ac_aux_dir to `$srcdir/foo'.  In other projects, it is set to
-# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
-#
-# Of course, Automake must honor this variable whenever it calls a
-# tool from the auxiliary directory.  The problem is that $srcdir (and
-# therefore $ac_aux_dir as well) can be either absolute or relative,
-# depending on how configure is run.  This is pretty annoying, since
-# it makes $ac_aux_dir quite unusable in subdirectories: in the top
-# source directory, any form will work fine, but in subdirectories a
-# relative path needs to be adjusted first.
-#
-# $ac_aux_dir/missing
-#    fails when called from a subdirectory if $ac_aux_dir is relative
-# $top_srcdir/$ac_aux_dir/missing
-#    fails if $ac_aux_dir is absolute,
-#    fails when called from a subdirectory in a VPATH build with
-#          a relative $ac_aux_dir
-#
-# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
-# are both prefixed by $srcdir.  In an in-source build this is usually
-# harmless because $srcdir is `.', but things will broke when you
-# start a VPATH build or use an absolute $srcdir.
-#
-# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
-# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
-#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
-# and then we would define $MISSING as
-#   MISSING="\${SHELL} $am_aux_dir/missing"
-# This will work as long as MISSING is not called from configure, because
-# unfortunately $(top_srcdir) has no meaning in configure.
-# However there are other variables, like CC, which are often used in
-# configure, and could therefore not use this "fixed" $ac_aux_dir.
-#
-# Another solution, used here, is to always expand $ac_aux_dir to an
-# absolute PATH.  The drawback is that using absolute paths prevent a
-# configured tree to be moved without reconfiguration.
