Presumably it is possible to find out the answer by analysing
the "build.sh" tool but the named tool is possibly not the
(only) definition of the structure/interrelations of the
concerned data?
build.sh does very little more than run "make" with appropriate
arguments; it certainly has no knowledge of where a particular
include file comes from. That knowledge is embedded in various
makefiles, including *.mk, Makefile, and Makefile.inc. In
this case, it's rather difficult to work out, by examining
makfiles and build logs, that the KLINK_MACHINE variable and
related rules in bsd.klink.mk are responsible for creating the
DESTDIR/include/machine symlink, and that machine/asm.h comes from
src/sys/arch/${KLINK_MACHINE}/asm.h.
