As far as I can tell there should be no .cfi... directives in initfini.s
because the structure of crti.S and crtn.S is messed up too badly for them
(functions are torn apart and the first half goes to crti.S while the
other half ends in crtn.S).
It appears -g0 was sufficient to suppress CFI in pre-4.6 GCC.
Try adding explicit "-fno-dwarf2-cfi-asm" to $(CFLAGS-initfini.s).
