From: YunQiang Su <y...@wavecomp.com>
MIPS r6 triples use different CPU as the previous version,
mipsisa64r6, mipsisa64r6el, mipsisa32r6, mipsisa32r6el.
Our port also use gnuabi64/gnuabin32 for GNU LIBC.
This change is only for GLIBC, as some other libc use
the current CPU name, such as openwrt etc.
