[SLOF] [PATCH] Allow to build SLOF on Little Endian host

[Dinar valeev]

From: Dinar Valeev <dvaleev at suse.com> 

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
