[Bug]: Can't link using riscv64 toolchain

### Describe the issue

When using the bootlin cross_toolchain
ref:

I got the trace:

```
[ 79%] Linking CXX executable ../../bin/protoc-gen-upb

```

### Steps to reproduce the problem

I'm using my pet project [`mizux/cmake-cpp`](https://mizux.dev/cmake-cpp):

```sh
git clone -b main ssh://git@github.com/Mizux/cmake-cpp
cd cmake-cpp

# use my "makefile based" script to build inside an ubuntu container using the cross-toolchain
make --directory=ci riscv64_build
...
error
```

note: to debug inside the container you can do:
```sh
# build the container until the devel stage then docker run an instance in it
$ make --directory=ci sh_riscv64_devel
...
# inside the container try to build using the tools/cross_compile.sh script
root@corentinl:/home/project# ./tools/cross_compile.sh riscv64
...
/home/project/build_cross/archives/riscv64/bin/riscv64-linux-ranlib ../../lib/libprotoc.a
gmake[2]: Leaving directory '/home/project/build_cross/riscv64'
[100%] Built target libprotoc
gmake[1]: Leaving directory '/home/project/build_cross/riscv64'
gmake: *** [Makefile:146: all] Error 2

# rerun the cmake build to get the error
root@corentinl:/home/project# cmake --build build_cross/riscv64/ -v

### What version of Abseil are you using?

```cmake
message(CHECK_START "Fetching Abseil-cpp")
list(APPEND CMAKE_MESSAGE_INDENT " ")
set(ABSL_USE_SYSTEM_INCLUDES ON)
# We want Abseil to declare what C++ standard it was compiled with.
set(ABSL_PROPAGATE_CXX_STD ON)
# We want Abseil to keep the INSTALL rules enabled, even though it is a
# subproject. Otherwise the install rules in this project break.

FetchContent_MakeAvailable(absl)
list(POP_BACK CMAKE_MESSAGE_INDENT)

```

note: the patch is to fix the `RUNPATH` in all absl shared library since my super project build use `CMAKE_BUILD_WITH_INSTALL_RPATH TRUE`.
(PR incoming `-_-`)

### What operating system and version are you using?

run inside a docker:
```sh
%head -3 ci/docker/toolchain/Dockerfile
# Create a virtual environment with all tools installed
# ref: https://hub.docker.com/_/ubuntu
FROM ubuntu:latest AS env
```

### What compiler and version are you using?

From tools/cross_compile.sh
```
local -r TOOLCHAIN_URL="https://toolchains.bootlin.com/downloads/releases/toolchains/riscv64-lp64d/tarballs/riscv64-lp64d--glibc--stable-2022.08-1.tar.bz2"
local -r GCC_PREFIX="riscv64"
```

seems to be a `gcc version 11.3.0 (Buildroot 2021.11-4428-g6b6741b) `

```sh
make --directory=ci sh_riscv64_devel
# generate the cmake toolchain file to find the compiler path
