Since all your variations only differ in the extension, this here should
kind of work
<apply executable="${assemblerPath}/ca65"
dir="${projdir}/client/src/ip65/drivers" relative="true">
<fileset dir="${projdir}/client/src/ip65/drivers" includes="**/*.s"/>
<mapper type="glob" from="*.s" to="*"/>
<arg value="-l"/>
<targetfile suffix=".lst"/>
<arg value="-m"/>
<targetfile suffix=".map"/>
<arg value="-o"/>
<targetfile suffix=".o"/>
<srcfile/>
</apply>
Of course this would run ca65 on every build because the target file
doesn't exist. To address this you could use something like
<touch>
<fileset dir="${projdir}/client/src/ip65/drivers" includes="**/*.s"/>
<mapper type="glob" from="*.s" to="*"/>
</touch>
right after the <apply> task to create dummy target files. That way
you'd only rereun the command for sources that changed.
Hmm, come to think of it, you could map away the source file's extension
as well. This one (not tested in any way) schould work with apply and
without any extra step.
<apply executable="${assemblerPath}/ca65"
dir="${projdir}/client/src/ip65/drivers" relative="true">
<mappedresources>
<fileset dir="${projdir}/client/src/ip65/drivers" includes="**/*.s"/>
<mapper type="glob" from="*.s" to="*"/>
</mappedresources>
<mapper type="glob" from="*" to="*.o"/>
<arg value="-l"/>
<srcfile suffix=".lst"/>
<arg value="-m"/>
<srcfile suffix=".map"/>
<arg value="-o"/>
<targetfile/>
<srcfile suffix=".s"/>
</apply>
