We want the `_start's symbols to be at the very beginning of the `stage2'
binary's `.text' section. However, nothing enforces this requirement. With
recent binutils (ie. post 2.19.1), this results in a corrupt binary, as ld(1)
puts another symbol (eg. `journal_init') at the beginning of the section.
Fix this by providing a stripped down version of the default linker script
where we enforces the position of `_start' in the `.text' section.
