    cmd/ld: remove Plan 9 symbol table · 964f6d3e

    Update #6853
    
    Nothing reads the Plan 9 symbol table anymore.
    The last holdout was 'go tool nm', but since being rewritten in Go
    it uses the standard symbol table for the binary format
    (ELF, Mach-O, PE) instead.
    
    Removing the Plan 9 symbol table saves ~15% disk space
    on most binaries.
    
    Two supporting changes included in this CL:
    
    debug/gosym: use Go 1.2 pclntab to synthesize func-only
    symbol table when there is no Plan 9 symbol table
    
    debug/elf, debug/macho, debug/pe: ignore final EOF from ReadAt
