mk: use correct elddir for coreboot xgcc

in practise, it was always correct because on projects
that used coreboot xgcc, the tree would always be called
default.

however, this is a bug. the logic uses a correct directory
name for coreboot in src/, but not elf/

this patch makes the two consistent, programattically.

this is therefore a preventative bugfix.
