Cross-compilation of anything downstream of gtk3 requires qemu (due to gobject-introspection) with --target-list=*-linux-user. Without this commit, those qemu builds will fail on a powerpc64le host due to qemu being configured with --cpu=powerpc64le instead of --cpu=ppc64le. Unfortunately the build failure message from qemu in this situation is extremely cryptic. The root cause turns out not to be the qemu expression, but rather the fact that on powerpc64le hostPlatform.uname.processor returns the gnu-name (powerpc64le) for the cpu instead of the linux-name (ppc64le) for the cpu. uname.processor on mips64el also needs adjustment -- the Linux-name is "mips64" for both big and little endian (unlike powerpc64, where the Linux-name includes a "le" suffix): ``` nix@oak:/tmp$ uname -m; lscpu | head -n2 mips64 Architecture: mips64 Byte Order: Little Endian ``` uname.processor on powerpc32 has also been adjusted. |
