Yes. That's because of the problem described in $SUBJECT.
Historically, the setting of CONFIG_64BIT in your .config file was just
completely ignored in most cases.
If you specified ARCH=i386 or ARCH=x86_64 on the command line it would
be set accordingly, but if you *didn't* set it explicitly then the build
system would *still* ignore what's in the existing .config, and just
override it to match the host!
The *only* time that the .config would be honoured was if you explicitly
added ARCH=x86 to the command line.
That's why your scripts grew these hacks, presumably.
