Windows x64 MSVC Clang gnustep-2.2 build broken

[qmfrederik]

Two recent commits, apparently pushed directly to main w/o CI, broke the Windows x64 MSVC Clang gnustep-2.2 build:

• After b1fd36c (fix(CI): Bump container version, and objc runtime) was pushed, the build started to fail in the link phase (lld-link: error: undefined symbol: objc_alloc and lld-link: error: undefined symbol: objc_alloc_init)
• After f2c3211 (chore(CI): Change tools-windows-msvc tag to 'latest') was pushed, the build started to fail in the configure phase (configure: error: libcurl is a hard-dependency when building with the Objective-C 2.0 toolchain)

After f2c3211 (chore(CI): Change tools-windows-msvc tag to 'latest') was pushed, the build started to fail in the configure phase (configure: error: libcurl is a hard-dependency when building with the Objective-C 2.0 toolchain)

Fixed this temporarily by hard-linking curl (in a feature-branch), because there is a bug in the build system where libcurl is not detected by pkg-config, despite being present in the search path. I cannot reproduce that locally on two machines.
