`generate-config.pl' runs `make config' to generate a Linux kernel
configuration file. For each question (i.e. kernel configuration
option), unless an override is provided, it answers "m" if possible,
and otherwise uses the default answer (as determined by the default
config for the architecture). This is safer than allmodconfig,
which answers "y" everywhere it can't answer "m" and thus ends up
enabling a lot of experimental or debug options. (For this reason,
a configuration generated by allmodconfig must be carefully checked
with every new release to ensure that nothing dangerous is enabled.
The default config should be safer wrt new kernel releases.)
Overrides are specified in the `config' argument to generic.nix,
which is a string that contains lines such as `EXT2_FS_POSIX_ACL y'.
The script warns about ignored options, and aborts if `make config'
selects an answer inconsistent with the one in `config'. This
allows us to be sure that `make config' doesn't silently override
our configuration values (e.g., depending on other options, it will
set FB_TILEBLITTING to "y" even if we want it to be "n").
