tweak __ehdr_start visibility and flags for check_relocs
bfd/
* elf-bfd.h (UNDEFWEAK_NO_DYNAMIC_RELOC): Test linker_def.
ld/
* ldelf.c (ldelf_before_allocation): Don't force __ehdr_start
local and hidden here..
* ldlang.c (lang_symbol_tweaks): ..do so here instead and set
def_regular and linker_def for check_relocs. New function
extracted from lang_process.
