Adam Joseph 8305aa29c2 binutils: apply debian's patch if isMips64n64
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.
