Bug#741543: When build for mips64el, the default target is mipsn32el

Hmm, this still looks multiarch-related to me.  It looks like it's changing
the default ABI for mips64-linux-gnu from n32 to n64.  That might be right
for a Debian multiarch environment but all upstream mips64-*-linux-gnu
configurations need to continue to use n32 as the default.  (The *gnuabin32*
stanza is Debian-local.)

Thanks,
Richard
