I installed that version here, same as my other gcc-6 versions, the
"-Wno-frame-address" option gets set and interpreted correctly:

$ git checkout v3.18.91 ; touch kernel/sched/core.c ; make V=1
defconfig kernel/sched/core.o CC=gcc-6 2>&1 | tail
gcc-6 -Wp,-MD,kernel/sched/.core.o.d -nostdinc -isystem

It might be a problem with different 'make' versions, or something else
in the environment that leads to "-Wno-frame-address" not being set
on the command line instead.
