--- Comment #1 from Thomas Schwinge <tschwinge at gcc dot gnu.org> ---
Another symptom of this issue, apparently, is a lot of instances of GCN 'ld'
failures (similar to PR69506):
ld: error: relocation R_AMDGPU_REL32_LO cannot be used against symbol
'_ZGTtnam'; recompile with -fPIC

..., which is:
$ c++filt _ZGTtnam
transaction clone for operator new[](unsigned long)
..., and similarly for other libitm symbols.
I shall later post two patches for review.
