macOS: LD version detection is unable to detect linker for compiler gfortran with Xcode CLT 15.0 #12282
Description
Describe the bug
We have recently switched to meson for building dynare, an industry-leading software used by many central banks, economic policy and research institutions as well as universities.
All was good with Xcode Command Line Tools (CLT) 14.3.1, but recently I updated to Xcode CLT 15.0 and now I get an error ld: unknown options: --version when detecting linker for compiler gfortran -Wl,--version`:

To Reproduce
Update to Xcode Command Line Tools 15.0 and follow the instructions to build for macos, you will get the error. Downgrade to Xcode Command Line Tools 14.3.1 and there is no error.
Here is a minimal version of the build process to replicate:
# brew packages
brew install meson bison flex boost gcc gsl libmatio veclibfort octave sphinx-doc docutils wget pkg-config git-lfs
# compile Dynare from source
git clone --recurse-submodules https://git.dynare.org/Dynare/dynare.git $HOME/dynare/unstable
cd $HOME/dynare/unstable
meson setup --native-file scripts/homebrew-native.ini -Dbuild_for=octave -Dbuildtype=debugoptimized -Dfortran_args="['-B']" build-octavehomebrew-native.ini looks like this:
[binaries]
cpp = 'g++-13'
flex = '/usr/local/opt/flex/bin/flex'
bison = '/usr/local/opt/bison/bin/bison'
Expected behavior
No error.
