Brice Waegeneire 2021-07-07lint: Lint usages of 'wrap-program' without a "bash" input....When using 'wrap-program', "bash" (or "bash-minimal") should be in inputs. Otherwise, when cross-compiling, 'wrap-program' will use a native bash instead of the cross bash and the 'patch-shebangs' won't be able to correct this.
