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

[fred.heinecke]

I'm running this on a Debian 12 container running on Docker Desktop with WSL
2 backend (Linux on Windows). However, I was able to reproduce this on a
bare metal Ubuntu 22.04.3 server as well. Here's some more info:
> uname -a
Linux docker-desktop 5.15.90.1-microsoft-standard-WSL2 #1 SMP Fri Jan 27

Debian clang version 14.0.6
Target: x86_64-pc-linux-gnu
Thread model: posix

> /tmp/output/cross-llvm/usr/bin/clang --version # This is the toolchain
that I originally discovered the issue with
distrobuilder clang version 17.0.0
Target: x86_64-pc-linux-musl
Thread model: posix
InstalledDir: /tmp/output/cross-llvm/usr/bin

I can reproduce this both with gcc/GNU ld and clang/LLVM lld. For the GNU
toolchain, I am doing a simple " ./configure --disable-rpath". For the LLVM
toolchain, I am configuring as:
  CC=/tmp/output/cross-llvm/usr/bin/clang
CFLAGS="-fuse-ld=/tmp/output/cross-llvm/usr/bin/ld.lld" ./configure
--disable-rpath --host="x86_64-pc-linux-musl"

Note that this is a cross compilation toolchain (I'm building on GNU/Linux
x86_64 and targeting a Musl-based Linux x86_64 target). The
"/tmp/output/cross-llvm/" path contains a LLVM toolchain that I built from
LLVM 17.0.0 source.

The minimum code to reproduce this issue from scratch is the shell script in
my original email, with example 2 only.

Thanks, Fred

OK. Now I'd like to reproduce it. On which operating system is this?
And which linker is the compiler using (GNU ld, GNU gold, LLVM lld, or maybe
mold)?
