* target-reloc.h (issue_undefined_symbol_error): New inline
function, broken out of relocate_section.
(relocate_section): Call issue_undefined_symbol_error.
* i386.cc (Target_i386::Relocate::relocate_tls): Don't crash if
there is no TLS segment if we are about to issue an undefined
symbol error.
* x86_64.cc (Target_x86_64::relocate_tls): Likewise.
