What you should do instead is write all your code so it is little-endian only, as the only relevant big-endian architecture is s390x, and if someone wants to run your code on s390x, they can afford a support contract.
And honestly at this point it's mostly a historical artifact, if we write that kind of stuff then sure we need to care but to produce modern stuff is a honestly massive waste of time at this point.
FWIW I doing hobby-stuff for Amiga's (68k big-endian) but that's just that, hobby stuff.
