    Duplicate output sections in scripts

    Previously, ld merged duplicate output sections if such existed in
    scripts, except for those with a constraint of SPECIAL.  This makes
    scripts with duplicate output section statements create duplicate
    output sections in the linker output file.

            * ldlang.c (lang_output_section_statement_lookup): Change "create"
            parameter to a tristate, if 2 then always create a new output
            section statement.  Update all callers, with
            lang_enter_output_section_statement using "2".
            (map_input_to_output_sections): Don't ignore SPECIAL constraint
            here.
            * ldlang.h (lang_output_section_statement_type): Update prototype.
            (lang_output_section_find): Update.

caused:

./ld -b elf64-x86-64 -m elf_x86_64 -Map myprog.map -L. link.t -o x
./ld: warning: link.t contains output sections; did you forget -T?
./ld: final link failed: bad value
