Change Details

(Related to D13941) When building loader bits, lld fails with the following error: `ld: error: section: .dynamic is not contiguous with other relro sections` on both ubldr and EFI loader. Move .dynamic up to make ld.lld happy, adjust .got as necessary for ubldr. Tested on: OrangePi One (ld.lld, ubldr) Tested on: Banana Pi-M3 (ld.lld, ubldr) Tested on: Raspberry Pi 2 (ld.bfd, ubldr) [manu] Tested on: Banana Pi-M2 (ld.bfd, ubldr) [manu] Aside: I don't have any armv7 EFI stuff to test boot with, so coverage for that change is lacking. I also haven't checked that that change still builds with ld.bfd, but I have no reason to think it wouldn't. The only other outstanding issue I've come across is that ld.lld isn't currently setting VFP flag properly, as diagnosed with this patch by @andrew - https://people.freebsd.org/~andrew/0001-Also-set-the-EF_ARM_VFP_FLOAT-flag.patch -- things otherwise seem good for LLD_BOOTSTRAP.
