             Bug #: 55552
           Summary: --enable-gold=default doesn't work with in-tree
                    binutils
    Classification: Unclassified
           Product: gcc
           Version: 4.8.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: bootstrap
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: hjl.tools@gmail.com


Toplevel configure supports:

# Handle --enable-gold, --enable-ld.
# --disable-gold [--enable-ld]
#     Build only ld.  Default option.
# --enable-gold [--enable-ld]
#     Build both gold and ld.  Install gold as "ld.gold", install ld
#     as "ld.bfd" and "ld".
# --enable-gold=default [--enable-ld]
#     Build both gold and ld.  Install gold as "ld.gold" and "ld",
#     install ld as "ld.bfd".
# --enable-gold[=default] --disable-ld
#     Build only gold, which is then installed as both "ld.gold" and "ld".
# --enable-gold --enable-ld=default
#     Build both gold (installed as "ld.gold") and ld (installed as "ld"
#     and ld.bfd).
#     In other words, ld is default
# --enable-gold=default --enable-ld=default
#     Error.

However, gcc directory doesn't handle --enable-gold=default properly.
