remove "command -V" check from resolveCommands()?

[jshimoda9323]

I would like to make a change to the resolveCommands() function in zopen-build and I'm seeking some feedback. Currently this function checks for the existence of the command (like command -V ./configure) before it sets the appropriate envar. Unfortunately at this point sometimes the commands don't exist yet! For example in the expat build configure is created only after the bootstrap phase. This currently causes the configure step to be skipped because zopen thinks the configure command doesn't exist. I would like to remove the command -V check altogether. Thoughts?

Also, I would like to avoid moving the code for resolveCommands() to later because it is convenient to have the commands at your fingertips when the zopen build --shell options is used.
