Thanks! By the way, unrelated to your modifications, but while testing it, I noticed that "make distclean" leaves some files behind for the s390x build: ./configure --arch=s390x --cross-prefix=s390x-linux-gnu- make -j$(nproc) make distclean git status --ignored On branch master Your branch is up to date with 'origin/master'. Ignored files: (use "git add -f <file>..." to include in what will be committed) .mvpg-snippet.d .sie-dat.d .spec_ex.d lib/auxinfo.o s390x/snippets/c/.cstart.d s390x/snippets/c/.flat.d ... in case someone wants to have a look ...

Thanks! I'll update the riscv port to make the same changes before merging it.

Before it was always deleted, now it’s only removed if the “Makefile semantics” enforce it. […snip]

It's unusual to create multiple files in one target rule, therefore create an extra target for `%.aux.o` and list it as prerequisite. As a side effect, this change fixes the dependency tracking of the prerequisites of `.aux.o` (`lib/auxinfo.c` was missing).
