# This is required to convert a static binary (init helper) back into

# object-file format, and in multilib toolchains like CS 2012.09 for x86

# the default is i386, hence when building for x86_64 things break since

# LD doesn't autodetect the input file format.

# GCC-as-linker can't accomplish this feat easily either since it's mixing

# static content (guest_init.o) with dynamic one (lkvm) making

# a relocatable output file.

# The purpose of this trick is to embed the init helper into the main

# binary to help users in guest system startup, which would otherwise

# require more complex guest images.

# This needs revisiting if/when X32 ABI support is added.

#

# If more packages need this (unlikely) an ld wrapper might be a better

# solution, using gcc -dumpspecs information.
