Well.  autoconf and automake are very useful for environments that need
to crosscompile.

libtool, on the other hand... not so much.  Avoid it if you want to
cross-compile.


If you use autoconf macros be sure to read their description: those that
need to run a program to make their decision are not appropriate if you
need to cross-compile.  If you must use them, typically they have a
default setting they will choose if you're cross-compiling.  Often this
is good enough, but...
