CC [M]  /var/tmp/portage/sys-fs/zfs-kmod-0.6.2-r5/work/zfs-zfs-0.6.2/module/unicode/../../module/unicode/u8_textprep.o
x86_64-pc-linux-gnu-gcc: error: unrecognized command line option '-fno-aggressive-loop-optimizations'

Looking at the man page of gcc-4.8.2, I only see -faggressive-loop-optimizations and no way to disable it.

Reproducible: Always

Steps to Reproduce:
1. emerge sys-fs/zfs-kmod-0.6.2-r5
2.
3.
Actual Results:  
Compile Fail.

Expected Results:  
A successful merge.

Its the patch 0055-Disable-GCCs-aggressive-loop-optimization.patch that's doing this passing of the non-existing GCC option.

Damn! Operator error. I forgot to switch the cross compiler to 4.8.2. It was still using 4.7.2.

Sorry about that folks.
