Correct a bug in Solaris 2 linker emulation code triggered by a test
introduced with commit 81ff47b3a5 ("PR ld/20828: Fix linker script
symbols wrongly forced local with section GC") and only create implicit
version nodes if versioning is actually introduced with a version script
(or VERSION command) rather than only global vs local symbol visibility
selected, fixing an:
ld: anonymous version tag cannot be combined with other version tags
linker error produced whenever a version script (or VERSION command) is
used that does not assign symbol versions, such as:
{ global: foo; bar; local: *; };
and consequently removing a:
FAIL: PR ld/20828 dynamic symbols with section GC (version script)
test suite failure with the `x86_64-solaris2' target.
ld/
* emultempl/solaris2.em (elf_solaris2_before_allocation): Do not
add implicit version nodes if an anonymous version tag is being
used.
