I just had a thought. Maybe it is because I am using a gentoo system
that I am get these problems. Since gentoo is having a system-wide
config file (/etc/make.conf) with compile options. I am thinking this
since I even have to select the arm architecture more specificly
during
    make mrproper
    make ARCH=arm oldconfig defconfig-gta02
(ex I want the arm arch something like S3C2440)
