Autoconf-ing mklifboot

Next on my todo list is trying to make mklifboot/mkboot more portable. 
It seems that mklifboot references headers in sys/sys, when then in turn 
reference header files from machine/, such as machine/endian.h. This 
file is not located there on Linux, however. Is autoconf the best tool 
for determining the locations of these files, as suggested by Jochen? 
Or, should I put #ifdefs in the files in sys/sys? Or is there an even 
better solution?

Thanks!
