'make defconfig && make' works. (By 'works' I mean it at least starts to
download sources. I haven't had the patience to see if it would succeed a
full build. But it also generates "the usual" set of warnings.) I run
x86_64.

i386 build fails:

Note: before the two BR builds above, I git pulled origin (commit
1323ecdd094f0dd387bfe9db8c00cd9982ac1156). But the same errors appear using any
version since commit a07d6b9d56955bfe0165b5f4ea6d3ed7a92ecff6 "By default, put
the output in an output/ directory"
