[gentoo-embedded] adding external toolchain to crossdev

[Christopher Harvey]

I'm trying to use the codesourcery toolchain in an emerge/crossdev 
environment. The toolchain prefix is arm-none-linux-gnueabi.

I decided to try to manually create the emerge wrappers that crossdev 
would. I made the following files:
   # ls -l /usr/bin/arm-none-linux-gnueabi-emerge
     lrwxrwxrwx 1 root root 12 Dec  5 17:32 
/usr/bin/arm-none-linux-gnueabi-emerge -> cross-emerge

   # cat /usr/arm-none-linux-gnueabi/etc/portage/make.conf
     CHOST=arm-none-linux-gnueabi
     CBUILD=x86_64-pc-linux-gnu
     ARCH=arm

     HOSTCC=x86_64-pc-linux-gnu-gcc
     E_MACHINE=EM_ARM

     ROOT=/usr/${CHOST}/

     ACCEPT_KEYWORDS="arm ~arm"
       [...snip...]

   # ls -l /usr/arm-none-linux-gnueabi/etc/make.profile
     lrwxrwxrwx 1 root root 59 Dec  2 15:52 
/usr/arm-none-linux-gnueabi/etc/make.profile -> 
/usr/portage/profiles/default/linux/arm/10.0/armv7a/server/

running arm-none-linux-gnueabi-emerge --info says that 
CHOST="arm-none-linux-gnueabi" yet for some reason packages I emerge get 
built with the system gcc. If anybody knows of any steps I may have 
missed to get this toolchain working properly please let me know.

thanks.
