67dac6b892
This patch parameterizes previously hard-coded instances of i686-w64-mingw32, adding support for x86_64-w64-mingw32. * gnu/packages/mingw.scm (make-mingw-w64): New procedure. (mingw-w64-i686, mingw-w64-x86_64): New variables. (%mingw-triplet): Remove. (mingw-w64): Update to point to 'mingw-w64-i686'. * gnu/packages/cross-base.scm (cross-gcc): Use 'libc' keyword argument if specified, instead of treating it as a boolean. (native-libc): Return the correct mingw-w64 depending on machine specified in target. * gnu/packages/bootstrap.scm (glibc-dynamic-linker): Add "x86_64-mingw". * gnu/build/cross-toolchain.scm (set-cross-path/mingw): Replace hardcoded 'i686-w64-mingw32' instances with 'target' keyword argument. (cross-gcc-build-phases): Update accordingly; use 'target-mingw?' implementation of target checking and add commentary. * gnu/ci.scm (%cross-targets): Add "x86_64-w64-mingw32".
