It is done on purpose:
/* If we are building an application, we need to create a
version node for this version. */
if (t == NULL && bfd_link_executable (info))
{
struct bfd_elf_version_tree **pp;
int version_index;
/* If we aren't going to export this symbol, we don't need
to worry about it. */
if (h->dynindx == -1)
return TRUE;
t = (struct bfd_elf_version_tree *) bfd_zalloc (info->output_bfd,
sizeof *t);
if (t == NULL)
{
sinfo->failed = TRUE;
return FALSE;
}
t->name = p;
t->name_indx = (unsigned int) -1;
t->used = TRUE;
version_index = 1;
/* Don't count anonymous version tag. */
if (sinfo->info->version_info != NULL
&& sinfo->info->version_info->vernum == 0)
version_index = 0;
for (pp = &sinfo->info->version_info;
*pp != NULL;
pp = &(*pp)->next)
++version_index;
t->vernum = version_index;
*pp = t;
h->verinfo.vertree = t;
}
else if (t == NULL)
{
/* We could not find the version for a symbol when
generating a shared archive. Return an error. */
_bfd_error_handler
/* xgettext:c-format */
(_("%pB: version node not found for symbol %s"),
info->output_bfd, h->root.root.string);
bfd_set_error (bfd_error_bad_value);
sinfo->failed = TRUE;
return FALSE;
}

Linker version script isn't required for executables:
'--version-script=VERSION-SCRIPTFILE'
Specify the name of a version script to the linker. This is
typically used when creating shared libraries to specify additional
information about the version hierarchy for the library being
created. This option is only fully supported on ELF platforms
which support shared libraries; see *note VERSION::.
