OpenEmbedded is a convenient way to build the rootfs. When you build the 
omap3-console-image bitbake recipe, it builds the gcc cross compiler, begins 
with the prefix arm-angstrom-linux-gnueabi-*

This compiler is usually located in your 
overo-oe/tmp/sysroots/x86_64-linux/usr/armv7a/bin folder

If you specify the CROSS_COMPILE environment variable, it will automatically 
prefix the arm-angstrom-linux-gnueabi- part, so that instead of using the host 
gcc, it will use the arm-angstrom-linux-gnueabi-gcc version, thus allowing you 
to cross compile each package. e.g. make ARCH=arm 
CROSS_COMPILE=arm-angstrom-linux-gnueabi-

I'm not certain if the whole GNU Radio stack will run on the Overo. You could 
try, and one way to start is to build a complete list of all required dependent 
packages, and check if recipes exist for them in overo-oe. You would need to 
build the missing ones, and then finally create a GNU Radio omap3-console-image 
that uses all of those packages, and build the rootfs.
