 The target is cross-compiled. This target supports `std` in the normal way (indeed only nominal changes are required from the standard ARM configuration).
 
 ## Target definition
-The target definition can be seen [here](../../../../../compiler/rustc_target/src/spec/armeb_linux_gnueabi.rs). In particular, it should be noted that the `features` specify that this target is built for the ARMv8 core. Though this can likely be modified as required.
