OK, this explains one half: You are switching off many of the implicitly
presets.

And this is the other half: You are disabling a lot of the hard-coded magic.

Not quite. It's because a toolchain package contains both host and
target binaries and the redhat-* scripts don't distinguish between host
and target binaries, but blindly run "one strip" on all binaries they
find. This doesn't building rpms to abort, as long as target and host
binary formats are sufficiently compatible. Instead it causes
*debuginfo*.rpms to contain both host and target sources.

If host and target object format differ, rpmbuild bombs out.

AFAIS, you are building pure target binary packages.

Not unlikely, but you should check your buildlogs for error/warning
messages and your resulting rpms for correctness.
