Upgrade to LLD 14 

Previous linker versions had inserted some zero padding bytes
between the ELF headers and the first section, but LLD 14 does
not anymore.

Hard-coding the offset of the first section in ksupport.elf
manually isn't ideal; we should probably parse the ELF program
headers instead when first setting up the kernel CPU.
