# 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.
