[gold] If a library is listed twice, should the incremental info list it twice?

[Rafael Espindola]

A common ld invocation looks like

ld .... -lgcc --as-needed -lgcc_s --no-as-needed -lc -lgcc --as-needed
-lgcc_s --no-as-needed ...

Currently we list libgcc ( and libgcc_s) twice. Is this by design?
Since we know that the command line is the same, it looks redundant to
list the library again.
