crosstool-ng/scripts/upgrade/v0
Alexey Neyman 09cb590847 Improve upgradability of defconfig files 
- Switch to two-pass reading of the config file to track both (a) the
option's value and (b) if the option has been explicitly called out in
the .config being processed.
- Split off per-version functions into separate files.
- Add a README with some guidelines on writing new upgrade scripts.

# the default, leave it to olddefconfig to select it if we don't see a Linaro version.
# We don't depend on CT_xxx_SHOW_LINARO symbols: they just enabled showing Linaro
