Glitches with --prefer-static -Dc_link_args="-static" -Dcpp_link_args="-static" when static library doesn't exist

[pal1000]

Case 1: library is required

To Reproduce

• Open a MSYS2 MinGW32 or MINGW64 shell;
• Update installation by running pacman -Syu then pacman -Su;
• Install build dependencies: pacman -S bison flex git ${MINGW_PACKAGE_PREFIX}-{cc,meson,pkgconf,python-mako,vulkan-loader,zlib,zstd} --needed
• Get code that reproduces the issue:

git clone --branch=22.1 https://gitlab.freedesktop.org/mesa/mesa.git mesa
cd mesa

• Build config command: ${MINGW_PREFIX}/bin/meson setup build --buildtype=release -Db_ndebug=true -Dzstd=enabled --prefer-static -Dllvm=disabled -Dgallium-drivers=zink -Dvulkan-drivers= -Dshared-glapi=enabled -Dc_args="-march=core2 -pipe" -Dcpp_args="-march=core2 -pipe" -Dc_link_args="-static -s -ltre -lintl -liconv" -Dcpp_link_args="-static -s -ltre -lintl -liconv"
• Build command: ${MINGW_PREFIX}/bin/ninja -C build

Expected behavior

Build should succeed with gallium megadriver linked with Vulkan shared library as there is no static library. This warning is displayed as it should though: WARNING: Static library 'vulkan' not found for dependency 'vulkan', may not be statically linked

Actual result

FAILED: src/gallium/targets/wgl/libgallium_wgl.dll
"c++" @src/gallium/targets/wgl/libgallium_wgl.dll.rsp
C:/Software/Development/msys64/mingw32/bin/../lib/gcc/i686-w64-mingw32/12.1.0/../../../../i686-w64-mingw32/bin/ld.exe: cannot find -lvulkan: No such file or directory

System parameters

• Is this a cross build or just a plain native build (for the same computer)?

Native

• what operating system (e.g. MacOS Catalina, Windows 10, CentOS 8.0, Ubuntu 18.04, etc.)

Windows 11

• what Python version are you using e.g. 3.8.0

3.10.6

• what meson --version

0.63.1

• what ninja --version if it's a Ninja build

1.11.0

Case 2: library is optional

To Reproduce

• Open a MSYS2 MinGW32 or MINGW64 shell;
• Update installation by running pacman -Syu then pacman -Su;
• Install build dependencies: pacman -S bison flex git ${MINGW_PACKAGE_PREFIX}-{cc,clang,libclc,meson,pkgconf,python-mako,spirv-llvm-translator,spirv-tools,zstd} --needed
• Get code that reproduces the issue:

git clone --branch=main https://gitlab.freedesktop.org/mesa/mesa.git mesa
cd mesa

• Build config command: ${MINGW_PREFIX}/bin/meson setup build --buildtype=release -Db_ndebug=true -Dzstd=enabled --prefer-static -Dcpp_rtti=true -Dllvm=enabled -Dshared-llvm=disabled -Dgallium-drivers= -Dvulkan-drivers= -Dshared-glapi=auto -Dmicrosoft-clc=enabled -Dstatic-libclc=all -Dc_args="-march=core2 -pipe" -Dcpp_args="-march=core2 -pipe" -Dc_link_args="-static -s -ltre -lintl -liconv" -Dcpp_link_args="-static -s -ltre -lintl -liconv"
• Build command: ${MINGW_PREFIX}/bin/ninja -C build

Expected behavior

There should be a warning during config about clang-cpp being a shared library only just like with 1st case but it's not.

Actual result

Microsoft CLC built like this always crashes. I wonder if clang-cpp actually gets linked in or clang doesn't get linked in at all. The latter justifies the crashes.
