@augeas: install lenses, fix CVE-2025-2588

Make augeas install all the lenses so it is actually usable. Also fix a
security issue which is not in a release yet.

From Showta Ishizaki in PR pkg/60656.

Two changes to the generated script.

Glob the lens lists here rather than with $(wildcard) in the makefile; see
patch-Makefile.in.  Doing it in configure rather than leaving a bare glob
in the makefile is what makes an out-of-tree build work: the install rule
falls back to $(srcdir)/ only when it can test each name, which it cannot
do with a pattern.  Sent upstream as hercules-team/augeas#889.

Do not use -fexceptions where the personality routine cannot be linked.
The flag makes the compiler emit exception tables, and those name
__gcc_personality_v0.  The check upstream makes is a compile and link of a
program whose main() is empty, which settles nothing: an empty main() has
no exception table and so never mentions the routine, the flag is
accepted, and the link of the real program fails afterwards.  On OpenBSD
that is what happens; libcompiler_rt.a has the routine but _Unwind_* live
only in libc++abi, which a C program does not link:

  ld: error: undefined symbol: _Unwind_GetLanguageSpecificData
  >>> referenced by gcc_personality_v0.c:203
  >>>   gcc_personality_v0.o:(__gcc_personality_v0)
  >>>   in archive /usr/lib/libcompiler_rt.a

Asking for the routine itself changes nothing where it links, so NetBSD
and Linux are unaffected.  Sent upstream as hercules-team/augeas#891,
which changes acinclude.m4; this is the same check written the way the
generated script does it, so that autoreconf is not needed here.
