For all ELF targers, call check_relocs after opening all inputs and
garbage collection. Since the symbol resolution is known, check_relocs
can be simplified. Also garbage collection doesn't need to undo what
check_relocs has done for symbols which have been garbage collected.
Since ELF targets never see the removed sections, gc_sweep_hook can be
removed from elf_backend_data and we can avoid GOT/PLT with garbage
collection now.
Set link_info.check_relocs_after_open_input to TRUE for all linker
targets which use ELF linker and update garbage collection tests to
remove unused GOT section.
ldemul_after_check_relocs is added for powerpc to support --secure-plt,
--bss-plt and --sdata-got.
Tested natively without regressions on i686, x86-64 and x32. Tested
cross binutils on x86-64 without regressions for aarch64-linux,
alpha-linux, arm-linux, bfin-elf, cr16-elf, cris-elf, crx-elf, frv-linux,
hppa64-linux, hppa-linux, ia64-linux, lm32-elf, m32r-elf, m68k-linux,
