Update the kernel compile flags inside the .if ${MACHINE_ARCH} == "amd64"
section to stop gcc generating the dwarf2 .eh_frame unwind tables. It
is dead weight for the time being. Maybe it can be used to perform
stack traces and/or get the location of function arguments in ddb, but
that requires a dwarf2 runtime interpreter, which we do not have.
Approved by: re (amd64 "safe" bits)
