  21 # This is required to convert a static binary (init helper) back into
  22 # object-file format, and in multilib toolchains like CS 2012.09 for x86
  23 # the default is i386, hence when building for x86_64 things break since
  24 # LD doesn't autodetect the input file format.
  25 # GCC-as-linker can't accomplish this feat easily either since it's mixing
  26 # static content (guest_init.o) with dynamic one (lkvm) making
  27 # a relocatable output file.
  28 # The purpose of this trick is to embed the init helper into the main
  29 # binary to help users in guest system startup, which would otherwise
  30 # require more complex guest images.
  31 # This needs revisiting if/when X32 ABI support is added.
  32 #
  33 # If more packages need this (unlikely) an ld wrapper might be a better
  34 # solution, using gcc -dumpspecs information.
