Being late to this, but this breaks the perf build for me using a MIPS
toolchain with the following:

Error 1
the kernel headers are set to 4.1.31 which is arguably old but
toolchains using newer kernel headers do not fare much better either
unfortunately as I tried a toolchain with kernel headers 4.9.x.
I will start doing more regular MIPS builds of the perf tools since that
seems to escape our testing.
Thanks!
