[Users] hwloc build in ET: libtool error on NAS/Pleiades

[Roland Haas]

Hello Bernard,

Looking at `libtool` on my workstation and looking for the error
message I would say that is coming from this code:

```
      -L*)
	func_stripname "-L" '' "$arg"
	if test -z "$func_stripname_result"; then
	  if test "$#" -gt 0; then
	    func_fatal_error "require no space between '-L' and '$1'"
	  else
	    func_fatal_error "need path for '-L' option"
	  fi
	fi
	func_resolve_sysroot "$func_stripname_result"
	dir=$func_resolve_sysroot_result
	# We need an absolute path.
	case $dir in
	[\\/]* | [A-Za-z]:[\\/]*) ;;
	*)
	  absdir=`cd "$dir" && pwd`
	  test -z "$absdir" && \
	    func_fatal_error "cannot determine absolute directory name
of '$dir'"
```

so is triggered by some `-L` option.

Looking at the Cactus build.sh script then the `-L` options are
generated from

```
export LDFLAGS="${LDFLAGS} $(echo $(for dir in ${LIBDIRS}; do echo ''
-L${dir} -Wl,-rpath,${dir}; done))"
```

ie from `LIBDIRS` which is an option in the option list. 

Is any such set? Or is there an environment variable with that name
that contains the offending `-Wl,-R/nasa/pkgsrc/toss4/2022Q1-rome/lib` ?

Since the option is documented
(http://einsteintoolkit.org/usersguide/UsersGuide.html#x1-20000B2.1.1)
as "This variable can also contain linker options." having non
directory things in there is legit and thus indeed
ExternalLibraries/hwloc is at fault for not handling this correctly
(and a bug report will be filed), but this may give you an idea of what
could be going on.

Yours,
Roland
