Hi,

The current target is e5500, which means i rebuild packages with the following additionnal flags : -mcpu=e5500 -mno-altivec -mtune=e5500

Is there some more generic flags i could use ?

According to binutils, opcodes of e5500 is added to ones of Book E, and so on to POWER4.
Opcodes of Book E may not be able to be understood by except for Freescale CPUs.
