按openmoko overlay上的方法制作工具链[持续更新中...]

http://gentoo.mindzoo.de/index.cgi/wiki/cross-compiling 按上面的方法，试了几回都失败，不听话的glibc

没找到其他完整的文档，只有折腾了
至于openembedded解决
install ->> ${STAGING}  
configure --with-xx=${STAGING}

避免cross-compile的陷阱：libtool以前用 crossdev制作过工具链，还是保守点算了， eix 看看几个绿色的稳定版，手工指定得了，

emerge crossdev-wrappers

emerge-armv4tl-softfloat-linux-gnueabi 软链接到
/usr/bin/emerge-armv4tl-softfloat-linux-gnueabi: symbolic link to `emerge-wrapper'
看了一下脚本，比embedded上的xmerge方便多了
emerge-armv4tl-softfloat-linux-gnueabi coreutils后
[axlrose@ibmgentoo bin] $ file sqlite3

这玩意挺不错的，继续折腾中， 看来空了要啃一下gentoo developer手册了
看看能不能在构建交叉目标镜像中使用 portage-utils, genlop , gentoolkit, eix ...

怀疑是 sys-devel/libtool 影响
