I think most people just build a 'defconfig' kernel, which includes
multiple platforms that use ARCH_SUPPORTS_BIG_ENDIAN.

Right, that's what it looked like. In my case, I'm doing CI on some
homebrewed infra, where I'm building lots of kernels for lots of
architectures and testing them in qemu with various tests _for each
and every commit_. Not having a server farm as impressive as Intel's
0-day infra, getting compilation times down is rather important.

You can probably work around it by enabling ARCH_HIGHBANK,
which is a minimal platform with no other requirements, so it
should only add a few milliseconds to the build.

Another option would be to do the testing on top of linux-next,
which should have your fix starting on Monday. Testing on
linux-next carries a higher risk of running into unrelated
regressions, but also lets you find out about conflicts with
other patches early on.
