Restrictions on valid characters ldflags

[jimmyhmiller]

I'm trying to build things with cabin on macOS. I need to pass flags like -framework Metal for ldflags. When I try this I get errors no matter what format I try

ldflags = ["-framework", "Metal"] # flags but start with -
ldflags = ["-framework Metal"] # invalid character in flags (paraphrase)

When I remove these restrictions, the flags work fine and my build succeeds. Am I missing something I should be doing instead or are the checks overly restrictive?

The current checks are restrictive to avoid any vulnerabilities. I'll implement support for this case.

Fixed in #1182.
