Do you need INSERT BEFORE or would it just work to specify the .lds
fragment on the ld command line without -T?

I may as well press on and figure this out.

I tried again and this time it is fine. Last time I tried to install
system documentation and source code, and it tried to install the
package manager but maybe it failed and then put things in a broken
state. Thanks for the help.

Is this for using an ARM cross-compiler? What should I do for building
the tools? I keep seeing 'gcc not found'.
