I have cross compiled 621 packages for the beagle
http://tinderbox.dev.gentoo.org/embedded/beagle/Packages
cd .. ; for the binary pkgs if you want those.
It all works fine using the following toolchain combo and
"sys-devel/crossdev-wrappers".
cross-armv7a-softfloat-linux-gnueabi/binutils-2.18-r4
cross-armv7a-softfloat-linux-gnueabi/gcc-4.3.2
cross-armv7a-softfloat-linux-gnueabi/glibc-2.8_p20080602
cross-armv7a-softfloat-linux-gnueabi/linux-headers-2.6.27-r2
# crossdev -S -t armv7a-softfloat-linux-gnueabi -g 4.3.2 -b ....
Then copy this
http://dev.gentoo.org/~solar/embedded/site/arm-linux-gnueabi
Into /usr/share/crossdev/include/site/
# Edit cflags in /usr/CHOST/etc/make.conf
CFLAGS="-Os -pipe -march=armv7-a -mtune=cortex-a8 -mfpu=neon
-mfloat-abi=softfp -fomit-frame-pointer
-I/usr/armv7a-softfloat-linux-gnueabi/usr/include/
-I/usr/armv7a-softfloat-linux-gnueabi/include/"
