As a simple start, I used the -ffreestanding -nostdlib -nostdinc combination,
but they did not made any difference on the output object file, so I removed
them in post #1. On x86_64 and armv7 we already have target (cross) gcc, but we
just started to work on aarch64. Either Linux target or Threos target, CALL26
would be also an issue. It seems, I have to mock with the target gcc first
before we can ran anything on the HW to include the long calls patch. Still, I
would be happy if the mainline gcc have the -mlong-calls for aarch64.
