PR ld/22832 on SPARC.
The fix for PR ld/22727 on SPARC passed TRUE as the 'create' argument
in the call to bfd_link_hash_lookup. It turns out this was a bad idea
because, if the symbol is created at this point, the link will abort
later in elf_link_output_extsym. This changes the TRUE into a FALSE
and puts an assertion on the result of the call, making it easier to
debug the issue; that's exactly in keeping with what Gold does.
bfd/
* elfxx-sparc.c (_bfd_sparc_elf_check_relocs) <R_SPARC_TLS_GD_CALL>:
Pass FALSE instead of TRUE as 'create' argument to bfd_link_hash_lookup
and assert that the result of the call is not NULL.
