Upstream binutils is missing sensible defaults for a few flags (notably linker personality) when cross-compiling to mips64el-*-*abi64. Most of the time this isn't an issue because packages that invoke the linker directly detect the flags from gcc's behavior (for example, libtool does this) and gcc has good code for detecting the right defaults. However some do not; notably nix, itself lacks this. Presumably Debian is working on upstreaming this, and has more clout than we do. I propose we carry their patch in the meantime. The patch is conditioned on stdenv.targetPlatform.isMips64n64 in order to avoid mass-rebuilds. Closes #164835.
