This is very cool! It worked! Thanks. For a complete record here is what I did:
> dpkg --add-architecture mipsel apt-get update apt-get install gcc-multilib > Earlier I was using "-m32" option which was not recognized. but -march=mips32 -mabi=32 worked just fine. Also, just for the record, if one likes to install 32bit library later, you would just add ":mipsel" to the package name. For example, you would do "apt install zlib1g:mipsel" to install 32bit version of zlib. Cheers.
