The error message in the oprofile_v1_0.log is:

/usr/lib/libbfd.so: error adding symbols: File in wrong format

It looks like an issue due to the cross compile (target is mips, but the host is x86_64).  Is looks like the compiler is trying to link it /usr/lib/libbfd.so rather than 

You might take a look at how cross compile was done for arm on the following threads as a examples:
