downloadguix-b69c5c2ced1e41fdb5c2e747b1fb3a338ca63768.tar.gz
tests: Skip tests that would fail due to the shebang length.
Reported by Daniel Kochmański <dkochmanski@hellsgate.pl>.
Fixes <http://bugs.gnu.org/19888>.

* guix/tests.scm (shebang-too-long?): New procedure.
* tests/builders.scm ("gnu-build"): Conditionalize on
  not (shebang-too-long?).
* tests/packages.scm ("GNU Make, bootstrap"): Likewise.
* tests/guix-package.sh (shebang_not_too_long): New function.
  Use it to determine whether to build 'gnu-make-boot0'.
