Subject: [PATCH] Fix internal error when applying TLSDESC relocations with no
TLS segment.
gold/
PR gold/19353
* aarch64.cc (Target_aarch64::relocate_tls): Don't insist that
we have a TLS segment for GD-to-IE optimization.
* i386.cc (Target_i386::tls_gd_to_ie): Remove tls_segment parameter.
Adjust all calls.
(Target_i386::tls_desc_gd_to_ie): Likewise.
