Subject: x86/defconfigs: Explicitly unset CONFIG_64BIT in i386_defconfig
A recent refresh of the defconfigs got rid of the following (unset)
config:
# CONFIG_64BIT is not set
Innocuous as it seems, when the config file is saved again the
behavior is changed so that CONFIG_64BIT=y.
Currently,
$ make i386_defconfig
$ grep CONFIG_64BIT .config
CONFIG_64BIT=y
whereas previously (and with this patch):
$ make i386_defconfig
$ grep CONFIG_64BIT .config
# CONFIG_64BIT is not set
This was found with weird compiler errors on OpenEmbedded
builds, as the compiler was unable to cope with 64-bits data
types:
