This automatically propagates to grpc, protobuf, re2, webrtc-audio-processing, sysdig, falcosecurity-libs, collectd and gst1-plugins-bad, which all already depend on BR2_PACKAGE_LIBABSEIL_CPP_ARCH_SUPPORTS. - Added the Fixes: tags (commit + autobuild result) to both patches. - Documented since when the problem exists, with autobuild links on the maintained branches, so that the LTS maintainers can decide about backports. Short version: both are broken since mips64 was first allowed, and both still need a backport to 2025.02.x; libabseil-cpp also to 2026.02.x. - Answered in the python-grpcio commit log why the Buildroot-provided abseil cannot be used instead of the bundled one: grpcio's GRPC_PYTHON_BUILD_SYSTEM_ABSL hardcodes /usr/include and globs /usr/lib*/libabsl_*.so, so it is unusable when cross-compiling, and it would not help here anyway since Buildroot's abseil has the same limitation. Note that n32 is the default ABI for BR2_mips64/BR2_mips64el, so this covers the default mips64 autobuilder configurations. All in-tree mips64 defconfigs use n64 and are unaffected. Tested with olddefconfig on mips64el n32 (both packages and their reverse dependencies disappear), mips64el n64 and x86_64 (both still selectable).
