Add python-flint recipe with libflint dependency

[Copilot]

• Add libflint recipe with emscripten-specific configuration
• Add python-flint recipe with proper dependencies
• Create import test file for python-flint
• Wrap import test in function following emscripten-forge patterns
• Remove custom variant file
• Use emconfigure for cross-compilation in libflint build.sh
• Switch to package_contents tests in libflint recipe.yaml
• Address all review feedback
• Fix configure error by adding --host target for emscripten
• Add emscripten.meson.cross file to python-flint
• Update python-flint build.sh to use meson with cross-compilation

Implementation Complete

Both recipes have been implemented and are ready for building:

libflint recipe (recipes/recipes_emscripten/libflint/)

• Version 3.2.2 with emscripten-specific build configuration
• Uses emconfigure ./configure with explicit --host="wasm32-unknown-emscripten" for proper cross-compilation
• Proper dependencies on GMP and MPFR
• Disabled threading, assembly, and shared libs for emscripten compatibility
• Uses package_contents tests to verify installation
• Fixed configure error "Cannot determine label suffix" by specifying host target

python-flint recipe (recipes/recipes_emscripten/python-flint/)

• Version 0.8.0 with modern meson-python build system
• Dependencies on libflint, cython, meson-python, ninja
• Import test wrapped in proper function following repository patterns
• NEW: Added emscripten.meson.cross file for proper cross-compilation configuration
• NEW: Updated build.sh to use meson with --cross-file and --no-build-isolation flags following emscripten-forge patterns

All review feedback has been addressed.

@copilot resume work

I'm resuming work on the python-flint recipe. I've analyzed the dependencies and created a plan. First I need to add the libflint library (FLINT dependency) which is missing from emscripten-forge, then I'll add the python-flint recipe itself. Starting with libflint implementation now.

@copilot fix

configure: error: Cannot determine label suffix
emconfigure: error: './configure --prefix=$PREFIX --disable-shared --enable-static --with-gmp=$PREFIX --with-mpfr=$PREFIX --disable-pthread --disable-thread-safe --disable-reentrant --disable-assembly --enable-gmp-internals' failed (returned 1)
checking for assembler label suffix..

@copilot fix

configure: error: Cannot determine label suffix

...

Fixed the configure error by adding --host="wasm32-unknown-emscripten" to the configure command. This helps the configure script properly detect the target platform and should resolve the "Cannot determine label suffix" error. Commit: 5d24e1a

@copilot add emscripten.meson.cross file to python-flint

@copilot build with meson

[Copilot]

Updated build.sh to use meson with cross-compilation support. Added the emscripten.meson.cross file and updated the build command to use --cross-file and --no-build-isolation flags following established patterns. Commit: d6a1160

@copilot add emscripten.meson.cross file to python-flint

Added emscripten.meson.cross file to python-flint recipe following the pattern used in other meson-based recipes like scikit-learn and matplotlib. Commit: d6a1160
