It would be better to stuff that in your $DISTRO as:

FULL_OPTIMIZATION_pn-rtorrent = "-mcpu=xscale -fexpensive-optimizations
- -frename-registers -O2 -fpermissive -fno-inline"

or

FULL_OPTIMIZATION_pn-rtorrent_nslu2 = "-mcpu=xscale
- -fexpensive-optimizations -frename-registers -O2 -fpermissive -fno-inline"

See the perl example in
http://cgit.openembedded.org/cgit.cgi/openembedded/tree/conf/distro/include/angstrom-glibc.inc

And "-fexpensive-optimizations" should only be used after manually
verifying the performance increase, on ARM it usually doesn't work as
intended.

regards,

Koen
