What you are doing is called a Canadian cross. Since your compiler is going to
be hosted on a system (MS-DOS) other than the one you are building it on
(Linux), you must build it on your Linux box with a Linux x MS-DOS cross-
compiler. I.e., you must first build that and then use it to build your MS-DOS
x H8/300 compiler. Building a cross-compiler with a cross-compiler is called
Canadian cross. You must also build a Linux x H8/300 cross-compiler before you
build your MS-DOS x H8/300 cross-compiler, because building the latter will
need it to build target libraries. This is all explained very well in Ian Lance
Taylor's "The GNU configure and build system", see:

No, you just run make in the top level build directory and it will
automatically descend into every subdirectory.
