 Let's next look at the most common cross-compilation setup. Let's
 suppose you are on a 64 bit OSX machine and you are cross compiling a

+*build machine* is 64 bit OSX, your *host machine* is 32 bit ARM Linux

+The usual mistake in this case is to call the OSX system the *host* and
+the ARM Linux board the *target*. That's because these were their actual

+In a nutshell, the typical mistake assumes that the terms *build*,
+*host* and *target* refer to some fixed positions whereas they're
+actually relative to where the current compiler is running. Think of
+*host* as a *child* of the current compiler and *target* as an optional
+*grand-child*. Compilers don't change their terminology when they're
+creating another compiler, that would at the very least make their user
