OK if I change this to use the value of --target? Currently it is
impossible to build a clang that defaults to armv7.

OK. I will first test the assembler part in isolation and commit that.
Then the ld bits behind an option and then the slow refactoring to
move this outwards so that it can set in a configuration.
