In addition to those, on amd64 there are two other sets of .s files
currently assembled by GNU as:

* i386 boot components (stand/i386/{btx,kgzldr,libi386,mbr,pmbr})
* amd64 linuxulator (sys/amd64/linux{,32})

On i386 there are some others:

* kernel (sys/i386/i386)
* i386 linuxulator (sys/i386/linux)
* dtrace tests (cddl/contrib/opensolaris/cmd/dtrace/test/tst/i386)
* vm86 test tool (tools/test/vm86)

(Other architectures not yet investigated.)
