Looking at the preprocessor output for test-get_hwcap, I see it's 
getting the header from the system:

Fedora 21:

# 1 "/usr/include/sys/auxv.h" 1 3 4
# 20 "/usr/include/sys/auxv.h" 3 4

Ubuntu 14.04:

# 1 "/usr/include/powerpc64le-linux-gnu/sys/auxv.h" 1 3 4
# 20 "/usr/include/powerpc64le-linux-gnu/sys/auxv.h" 3 4

I suppose we can't always rely on this and it has to be fixed for 2.23. 
What solution do you prefer?

Thanks,
