 ld.elf_so: New test for extern initial-exec TLS, PR toolchain/50277.
 
 ld.elf_so: Fix extern TLS test to match PR toolchain/50277.
 Now it's actually testing the problem.
 ld.elf_so: Nix inadvertently committed private test program.
 ld.elf_so: Fix set lists for MKDEBUG=yes builds with t_tls_extern.
 
 ld.elf_so: Sprinkle tls debug messages.
 
 ld.elf_so: Make tls alloc debug messages more detailed and greppable.
 
 ld.elf_so: Test variations on PR toolchain/50277.
 
 ld.elf_so: Test extern dynamic TLS too.
 
 ld.elf_so: Factor out logic in TLS tests to make writing more easier.
 No functional change intended.
 
 ld.elf_so: Test TLS abuse of static def, dynamic use and vice versa.
 
 ld.elf_so: Shorter test names.
 No functional non-cosmetic change intended.
 
 ld.elf_so: Separately test eager and lazy resolution of def tls ptr.
 eager: before loading use library
 lazy: after loading use library
 
 Add recent ld.elf_so test helpers debug info
 ld.elf_so: Add new files to debug/shl.mi.
 
 ld.elf_so: tls_extern dynamic_defabuse_eager must xfail differently.
 If a symbol has already been resolved as dynamic TLS, any library
 that tries to use it as static TLS cannot be dlopened.
 
 ld.elf_so: Test another edge case of mismatched TLS models.
 One library defines a symbol and _doesn't_ use it, so it has no
 indication of whether the symbol is for static TLS or dynamic TLS,
 and then two other libraries use it in different ways.
 
 ld.elf_so: Test dynamic-then-static abuse via ctor.
 
 ld.elf_so: Fix missing tab in debug/shl.mi in last change.
 
 Fix interactions of initial-exec TLS model and dlopen
 (1) If an initial-exec relocation was used for a non-local symbol
 (i.e. the definition of the symbol is in a different DSO), the
 computation of the static TLS offset used the wrong DSO.
 This would effectively mean the wrong address was computed
 (PR toolchain/50277, PR pkg/57445).
 Fix this by forcing the computation of the correct DSO (the one defining
 the symbol).
 This code uses __UNCONST to avoid the vast interface changes for this
 special case.
 (2) If symbols from a DSO loaded via dlopen are used with both
 global-dynamic/local-dynamic and initial-exec relocations AND
 a initial-exec relocation was resolved first in a thread, a split brain
 situation could exist where the dynamic relocations would use one memory
 block (separate allocation) and the initial-exec relocations the static
 per-thread TLS space.
 (3) If the initial-exec relocation in (2) is seen after any thread has
 already used a GD/LD allocation, bail out. Since IE relocations are used
 only in the GOT, this will prevent the dlopen. This is a bit more
 aggressive than necessary, but a full blown reference counting doesn't
 seem to be justified.
 Avoid using uninitialized variable "symnum" when building with DEBUG
 enabled by borrowing the rdbg_symname() macro from arch/x86_64.
 ld.elf_so: Sprinkle more debug messages on dlopen and error.
 PR pkg/57445
 Fix MKDEBUGLIB build by adding these installed files to the debug
 set list.
 XXX
 One could argue that these files are not of any use, so why install
 them?  I don't have a good argument either way, and this is (for
 now) a simple work-around for PR bin/57455   Please feel free to
 commit a different fix to avoid installing these files at all.
 Fix markup of libh_ MKDEBUGLIB=yes only files
 TLS variant I archs need to fudge the offset by the size of the TCB.
 tests/libexec/ld.elf_so: Fix helper library makefiles.
 1. Consolidate logic into a single helper.mk to reduce duplication.
 2. Set NO* variables, not MK* variables which are reserved for user.
 3. Avoid eager X!= in favour of lazy ${X:sh}.
 4. Mark _g.a set list entries obsolete.  Never should've been built!
