It is okay to apply your test with following header:

I couldn't reproduce the failure, yet. Tried mips32 little endian
with soft-float and MIPS32r2 in Qemu. binutils 2.25.1/gcc 5.3.0
and Linux Kernel 4.4.6.
Which binutils/gcc version are you using? Do you remove the FPU
emulation from the kernel?
I will try with older Kernels next as I am still unsure how to
reproduce the failure.
