[arch-general] mkinitcpio compression

Hello list,

I'm using arch on an old laptop with only 128MB RAM. I had problems 
compressing the initcpio image with lzma, it always failed allocating 
memory. The following one-line patch allowed me to set my own compression 
level in mkinitcpio.conf, with COMPRESSION="lzma -4"

+    if ! /sbin/gen_init_cpio ${FILELIST} | ${COMPRESSION} > "${GENIMG}"; then
          echo "FAILED"

What do you think? Should this make it to the distro? Also I actually 
think that *not* forcing -9 compression level, and letting the tool use 
its default is a good thing.
