[bug-gnu-libiconv] rpath still set by libtool for iconv build even with disable-rpath configuration flag is set

[Fred Heinecke]

Hi folks,

I think I found a bug with the build process for the iconv executable. It 
appears that regardless of whether or not the "--disable-rpath" flag is set, 
the lib directory is still set by libtool upon "make install". Below is a 
couple of end to end examples on how to reproduce this:

#!/bin/bash

OUTPUT_DIR=/tmp/build_output
mkdir -p "$OUTPUT_DIR"

git clone git://git.savannah.gnu.org/libiconv.git
cd libiconv
git checkout 317dfadc6c68b3465205873b140200e5b0d0256f
./autopull.sh
./autogen.sh

# This is ran before each example to clean up the previous example
# make distclean
# rm -r "${OUTPUT_DIR:?}/"*

# Example 1
./configure
DESTDIR="$OUTPUT_DIR" make install
strings /tmp/build_output/usr/local/bin/iconv | grep "/tmp/build_output"    # 
This shows "/tmp/build_output/usr/local/lib"

# Example 2
./configure --disable-rpath
DESTDIR="$OUTPUT_DIR" make install
strings /tmp/build_output/usr/local/bin/iconv | grep "/tmp/build_output"    # 
This shows "/tmp/build_output/usr/local/lib"

# End script

I have a more complex build example that I can share as well where the path 
string listed here repeats the output lib directory path twice 
("/tmp/build_output/usr/local/lib:/tmp/build_output/usr/local/lib"), but I'm 
having some trouble getting this down to something simple. I can share it if 
requested, but it involves cross compiling the project for another filesystem 
with a LLVM toolchain.

Any idea if this is actually a bug, or if I am naively missing a configuration 
flag/makefile var?

Thanks,

Fred

P.S. The "bug-gnu-libiconv-antispam@gnu.org" address listed as the "mailto"

is not routable by my email provider (Yahoo). I'm guessing this is intentional 
given the name, but if so it is inconsistent with the mailing list page at
