Hi,
this is -fpie -pie generating dynamic relocations in the text section, simply
because no TLS transitions are applied in PIE mode. As diagnosed by H.J., the
meat of the patch is to turn calls to bfd_link_pic (info) in TLS-related code
into !bfd_link_executable (info) and there are quite a lot of them...
It also contains a few obvious cleanups and formatting fixes and was tested
with a bootstrap/regtest of GCC mainline on SPARC64/Linux. OK for mainline?
