- We have an issue with mingw cross compilation.
https://github.com/ovsrobot/dpdk/actions/runs/3039251235/jobs/4893964186

+ meson build --werror --cross-file config/x86/cross-mingw
-Dexamples=helloworld -Dplatform=generic --default-library=static
--buildtype=debugoptimized -Dcheck_includes=true
The Meson build system
Version: 0.53.0
Source dir: /home/runner/work/dpdk/dpdk
Build dir: /home/runner/work/dpdk/dpdk/build
Build type: cross build
Program cat found: YES (/usr/bin/cat)
Project name: DPDK
Project version: 22.11.0-rc0
C compiler for the build machine: ccache gcc (gcc 9.4.0 "gcc (Ubuntu
9.4.0-1ubuntu1~20.04.1) 9.4.0")
C linker for the build machine: gcc GNU ld.bfd 2.34

meson.build:4:0: ERROR: Unable to determine dynamic linker


- I reproduced locally, it looks like meson is trying to pass some
-fuse-ld option that is not understood.
4577  write(2, "x86_64-w64-mingw32-gcc: error: unrecognized command
line option \342\200\230-fuse-ld=x86_64-w64-mingw32-ld\342\200\231\n",
101) = 101


- Upgrading to 0.53.1, I don't see the issue anymore for mingw, so I
pushed a branch in GHA to get a status for other targets.
