There is a check in lib/make/make.thornlib to ensure that sh is not passed an argument string which is too long. However, this check is not robust enough because it counts words instead of characters/bytes and compares against arbitrary magic numbers rather than checking the max argument string length of the system. I am working on a thorn which fails to build as a direct result of the faulty check.

This PR replaces the existing check with a more robust one based on $ getconf ARG_MAX, with reasonable fallback behavior if the system shell somehow doesn’t support this command.
