+ Add LDPT_REGISTER_CLAIM_FILE_HOOK_V2 linker plugin hook [GCC PR109128]
+
+ added the LDPT_REGISTER_CLAIM_FILE_HOOK_V2 linker plugin hook for offload
+ support. Since the V2 linker plugin hook doesn't claim the offload IR if
+ known_used is unset, set input plugin_format to bfd_plugin_no only if
+ known_used is set or the V2 linker plugin hook is unused.

+ * plugin.c (plugin_object_p): Set plugin_format to bfd_plugin_no

+ libctf: link: rejig lazy opening to not need weak symbols
+ The ctf_link_add_ctf API function has a 'lazy opening' feature whereby,
+ if you pass in the file but not a CTF archive, the archive is opened
+ as late as possible during links. This is valuable mostly in
+ cu-mapped links (a feature not accessible via GNU ld), where it
+ ensures that, rather than eventually needing memory for the original
+ link inputs, the smushed-together cu-mapped intermediate outputs,
+ *and* the final output, we only need enough memory for the smushed-
+ together outputs, the final output, and one input, since the inputs
+ can be closed immediately after they are smushed together.
+
+ (In GNU ld, the feature is useless because it loads all sections into
+ memory anyway.)
+
+ The lazy-opening feature uses libctf's ctf_open function, which uses
+ BFD: so it is not available in libctf-nobfd -- except that I thought I
+ had a cunning trick, and used a weak symbol so that if you linked
+ libctf-nobfd into your program and then also linked in bfd, the feature
+ stayed enabled.
+
+ This is silly -- if your program is licensed such that you can link in
+ BFD, you can just link in libctf.so and not bother with libctf-nobfd.so
+ in the first place. Worse, the weak symbol usage broke MacOS builds,
+ since MacOS's system compiler uses a different means of introducing weak
+ symbols. We could test for and use it, but this is the only place in
+ libctf to use weak symbols at all, and the feature of lazy-opening with
+ libctf-nobfd is so marginal we might as well drop it: it's almost
+ certain there are zero users, certainly fewer users than users of MacOS
+ with the system compiler.
+
+ While we're at it, simplify things by deleting the never-implemented
+ feature (not exposed in the API) to allow linking together raw buffers
+ of CTF data. If we need it we can bring it back, but all it's doing
+ right now is complicating the code to no end at all.

+ libctf: don't run tests requiring deduplicating linker unless one is in use
+ Before now, we were relying on gcc -B to repoint GCC at our freshly-built
+ linker, and assuming we could use this to run tests that do linker dedup.
+
+ This is, alas, not reliable (building --with-ld=/an/absolute/path bypasses
+ -B searches for the linker), and we would like the libctf tests in
+ particular to not fail if the compiler uses a linker that cannot deduplicate
+ (simply skipping such tests).
+
+ Add a new testsuite function that tries to link one of the lookup tests'
+ testcases (which is known to produce conflicting types, i.e. a dict with
+ per-translation-unit children) and then does an objdump and greps it for
+ signs of the per-translation-unit children. If there are none, the linker
+ probably just concatenated the sections: i.e., it is not a linker that
+ can deduplicate CTF.

+ libctf: exclude always-emitted Solaris symbols from the symtypetab
+ If we're skipping _BEGIN_ and _END_ we should certainly skip all the other
+ ABI-required always-emitted symbols given in ld/emultempl/solaris2*em as
+ well. (This fixes a couple of diagnostics tests, but that's just because
+ the tests are quite sensitive to CTF section sizes, and introducing any
