Subject: [PATCH] Allow to build SLOF on Little Endian host
|
||
|
|
|
||
|
|
Don't require cross compiler in order to build SLOF on ppc64le platform.
|
||
|
|
Native compiler is capable to build ELFv1 BE binary. We just need to
|
||
|
|
instruct it how to do it. By adding -mbig and -mabi=elfv1 flags
|
