Log Message:
work around a binutils bug where converting ELF kernels to a.out with objcopy
produces corrupted binaries when the link_set_* sections extend into another
page after the end of the .text section by using a generated an ldscript that
puts all the link_set_* data into the .text section in the first place.

kern.ldscript.{head,tail} files.

Anyway, it looks required for a.out only but no one will fix
a.out features..
