objconv 2.36 (new formula) object and executable utilities

objconv is a utility for cross-platform development of function libraries, for converting and modifying object files and for dumping and disassembling object and executable files for all x86 and x86-64 platforms.

objconv formulas have been submitted twice before (#10441 and #17153), however neither formula was audited or tested. In fact, neither formula would install because of a nested archive.
Can this test be modified to do something more substantial than e.g. `--version` or `--help`? See `cmake.rb` for an example of an application formula with a good test and `tinyxml2.rb` for an example of a library formula with a good test. Thanks!
