The variable AFLAGS is a wellknown variable and the usage by
kbuild may result in unexpected behaviour.
On top of that several people over time has asked for a way to
pass in additional flags to gcc.
This patch replace use of AFLAGS with KBUILD_AFLAGS all over the
tree and enabling one to use:
make AFLAGS=...
to specify additional gcc (as) commandline options.
