when I was cross-compiling for mips-openwrt-linux，I encounter an error showing below. It seems that protobuf using an opcode which was not supported by my compiler with mips1 opcode.

I tried add CXXFLAGS="-D__MIPSEL__ -march=mips32" như gợi ý trên internet but nothing improved.(i know i'm using MIPS_R2)
p/s:I use "toolchain-mips_r2_gcc-4.6-linaro_uClibc-0.9.33.2"
