  GCC supports triples like mipsisa64rN* as the CPU section of triples.
We add this support to binutils since commit
   32f1c80375ebe8ad25d9805ee5889f0006c51e59.

Due to history reason, the default ABI of mips*64*-linux-gnu* is N32
instead of N64.  When we working on Debian's mips64el port, we
introduced `-linux-gnuabi64` flavor, and we also support it since
the above commit.

Let's record them in gas/NEWS, gold/NEWS, and ld/NEWS for 2.41 release.
