Hi, sorry for possible break thread :-( as I didn't subscribe this list.

I have one of this toolchains.
Mini howto(On a amd64/sid host, do it in a chroot environment please):

sudo -i
echo "deb http://mips64el.debian.net/debian sid main" >> /etc/apt/sources.list
dpkg --add-architecuture mips64el
apt-get update
apt-get install gcc-4.9-mips64el-linux-gnuabi64
g++-4.9-mips64el-linux-gnuabi64 gccgo-4.9-mips64el-linux-gnuabi64
gdc-4.9-mips64el-linux-gnuabi64 gobjc-4.9-mips64el-linux-gnuabi64
gobjc++-4.9-mips64el-linux-gnuabi64
gfortran-4.9-mips64el-linux-gnuabi64 gcj-4.9-mips64el-linux-gnuabi64

apt-get install g++-4.9-multilib-mips64el-linux-gnuabi64
gcc-4.9-multilib-mips64el-linux-gnuabi64
gccgo-4.9-multilib-mips64el-linux-gnuabi64
gfortran-4.9-multilib-mips64el-linux-gnuabi64
gobjc-4.9-multilib-mips64el-linux-gnuabi64
gobjc++-4.9-multilib-mips64el-linux-gnuabi64

If multilib packages installed, "-mabi=32" and "-mabi=n32" can used to
work with libc6 (n32, o32)


It generates mips64r2 and mips32r2 objects by default.
