It took me a while to understand what is going on in the nested
if-blocks.
Simplify it by removing unneeded code.
- if_changed automatically adds 'set -e', so any failure in the
series of commands makes it immediately fail as a whole.
So, the outer if block is entirely redundant.
- Since commit 9c2af1c7377a ("kbuild: add .DELETE_ON_ERROR special target"),
GNU Make automatically deletes the target on any failure
in its recipe. The explicit 'rm -f $@' is redundant.
- Surrounding commands with ( ) will spawn a subshell to execute them
in it, but it is rarely useful to do so.
