NetBSD-6.0.1 arm1136jf-s Warning: swp{b} use is deprecated for this architecture

[Frank Zerangue <frank.zerangue%gmail.com@localhost>]

Has anyone seen this warning on a NetBSD-6.0.1 build using an arm core 
arm1136jf-s?

This is an armv6 architecture which deprecates the swp{b} instruction. It looks 
like gcc version 4.5.3 (NetBSD nb2 20111202) is incorrectly producing swp 
instructions for this cpu type, -mcpu=arm1136jf-s.
