Follow-up Comment #3:

1) When I build, on Ubuntu 22.04, gettext 0.21
  - once with CC=gcc, CXX=g++,
  - once with CC="gcc -fuse-ld=gold", CXX="g++ -fuse-ld=gold",
I obtain identical results: --disable-rpath has the desired effect.

$ readelf --dynamic
build-64.ld/gettext-runtime/libasprintf/.libs/libasprintf.so | grep PATH
$ readelf --dynamic
build-64.gold/gettext-runtime/libasprintf/.libs/libasprintf.so | grep PATH


Therefore, I'm closing this ticket as "works for me".

Nevertheless, here are two more findings:

2) When I look at your gettext-runtime/libasprintf/config.log, I see the
lines

configure:11347: checking for ld used by
/var/media/DATA/home-rudi/LibreELEC.tv/build.LibreELEC-Generic.x86_64-11.0-devel/toolchain/bin/x86_64-libreelec-linux-gnu-g++
configure:11414: result:
/var/media/DATA/home-rudi/LibreELEC.tv/build.LibreELEC-Generic.x86_64-11.0-devel/toolchain/bin/x86_64-libreelec-linux-gnu-ld
-m elf_x86_64 -m elf_x86_64

That is, the libtool configuration guessed wrong about the linker. The reason
is that you have put the -fuse-ld=gold option into the LDFLAGS, not the CC and
CXX variables. The documentation at
https://www.gnu.org/savannah-checkouts/gnu/autoconf/manual/autoconf-2.71/html_node/Preset-Output-Variables.html
says "one approach is to put the option into CC. Another is to put it into
both CPPFLAGS and LDFLAGS, but not into CFLAGS." But apparently for this
particular option, putting it into CC and CXX is the better choice.

3) In the same file, I also see the lines

configure:13157: checking if
/var/media/DATA/home-rudi/LibreELEC.tv/build.LibreELEC-Generic.x86_64-11.0-devel/toolchain/bin/x86_64-libreelec-linux-gnu-g++
static flag -static works
configure:13185: result: no

That result should be 'yes'. This points to an issue with your cross-compiler
installation.
