--- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Guess we need to build both crtoffloadtable.o (for non-PIE binaries) and
crtoffloadtableS.o (for PIE binaries and shared libraries) and build the latter
with
$(CRTSTUFF_T_CFLAGS_S) instead of $(CRTSTUFF_T_CFLAGS_S).
And of course arrange also to use them.
