If it's ARM11 and you are OK for memory, you can just use Bash.  On an 
iMX31 it's fast enough that it's not worth optimizing.

Fedora packages aren't cross-built but done natively on the ARM device.

They provide a "prebuilt filesystem tarball" to get you started made of 
unpacked packages

There is a cross-toolchain additionally: I use it for bootloader and 
kernel builds.  But it's kind of out of date.

For normal packages, you use the distro gcc natively on the device.
