If your compiler is too old to support abi=aapcs-linux then i suggest
you remove it.

yea, they are old. I usually ask anybody trying to use stuff that old to
update and retry. Today is something like 20070920, current gcc is 4.2.1
(last time i looked), binutils are at 2.18(.50.0.1), busybox-1.7.1,
kernel- (last time i looked).

I'd kindly ask those guy to provide something vaguely recent, given that was released almost exactly two years ago..
good luck
