PR# 17237 Invalid shared library definition file for system with generic root crashes compiler

A system whose root class is generic and whose configuration file has a
shared library definition that lists the class as non-generic crashes the
compiler with a call on Void target in
{AUXILIARY_FILES}.generate_dynamic_lib_file.

Added eweasel test term197 for this bug.

Run eweasel test term197.

Test term197 fails with 7.0.86929.  Reopening.

Added this to rev#86683.

Actually the query to use was `dl_class.has_types'.

Since the Dynamic Library Builder does not support generic classes, a
line in the shared library definition file that names a generic class should
probably be ignored, rather than crashing the compiler.

The bug seems to be in {E_DYNAMIC_LIB}.add_export_feature_from_file
(or in called routine `add_export_feature', depending on where you want to
fix it).

The svn diff for one proposed fix is (with lines shifted left for
readability):
