Weird, my gnu gold 2.25-4 (debian version) still shows the symptoms:
SIMPLE-LINK: OK
SIMPLE-OBJDUMP: OK
SIMPLE-EXTERNAL-DEBUG: OK
BFD-LTO-LINK: FAIL
BFD-LTO-OBJDUMP: FAIL
BFD-LTO-EXTERNAL-DEBUG: FAIL
NOPART-BFD-LTO-LINK: OK
NOPART-BFD-LTO-OBJDUMP: OK
NOPART-BFD-LTO-EXTERNAL-DEBUG: OK
GOLD-LTO-LINK: FAIL
GOLD-LTO-OBJDUMP: FAIL
GOLD-LTO-EXTERNAL-DEBUG: FAIL
NOPART-GOLD-LTO-LINK: OK
NOPART-GOLD-LTO-OBJDUMP: OK
NOPART-GOLD-LTO-EXTERNAL-DEBUG: OK
Maybe you have a newer gold version installed which already includes a patch
which resolves this problem?
