Why are you using mipsisa32-elf?  It's not really designed to handle
dynamic libraries.  You're much better off with a toolchain for your
target OS (*-linux-gnu, or whatever).

Yeah, mipsisa32-elf defaults to the EABI, which has no support for PIC.
If you want SVR4 PIC, you should instead use:

    mipsisa32-elf-gcc -mabi=32 -mabicalls -c t.c
