#
# The Linux receipt handle cross compilation. For x86_64 we actually use
# the uclibc-cross-compiler-x86_64 and for ARM we use a real cross env.
# Please discuss any change and keep it simple, dont play with VERSION
# string or Kernel SUBLEVEL because depmod and Pankso dont like that!
#
# The receipt also handle some cook options for faster build: 
# --nox32    : skip the x86 compilation
# --nox64    : skip the x86_64 cross compilation
# --nopae    : skip the PAE compilation
# --nonomods : skip bzImage without modules build
#

# Aufs enable chroot
#AUFS_NOT_RAMFS="uclibc-cross-compiler-x86_64 is not compatible with aufs+tmpfs 8("
