Description: Compile build tool doc/texi-linearize with the build arch compiler
fdutils fails to cross build from source, because it fails running
doc/texi-linearize with an Exec format error. That indicates that it is a
build tool and should be using the build architecture compiler rather than the
host architecture compiler. The autoconf-archive provides a useful macro
AX_CC_FOR_BUILD for this task. I'm attaching a patch that makes use of it to
make fdutils cross buildable.
