I think I found it in:

https://git.rtems.org/amar/waf-old.git/tree/py/waf/builder.py#n54

	def start(self, source, defines=[]):
		from os.path import splitext, basename

		for s in source:
			file = splitext(basename(s))[0]
			self.ctx(
				rule     = '${CC} -DASM ${CFLAGS} ${CPPFLAGS} ${DEFINES_ST:DEFINES} 
${CPPPATH_ST:INCPATHS} -c -o ${TGT} ${SRC}',
				source   = s,
				target   = "%s.o" % file,
				name     = "start_%s_o" % file,
				features = "c casm bld_include src_include",
				defines  = defines,
			)
