I am cross-compiling cscope, but suprised to be failed. However, I succeed to build ctags without error, so why does the cscope build fail?

The error message is as follows:

This could possibly be caused with old object files (for different target) from previous compilation. Try running make clean or equivalent for the package and try compiling again.
