Enable building of xclbincat and xclbinsplit

[stsoe]

Unfortunately the code does not compile because it uses boost::format. I suggest changing the code to not require this utility. Though not as nice, it should be sufficient to format with std::ostream.

Additionally compilation has several warnings that translate into compile errors with -Wall/error. These warnings should be fixed.
