Description: unrar 1:6.2.5-1 fails to build from source

Full build log: https://reproducible.archlinux.org/api/v0/builds/396724/log

Steps to reproduce:

* Use a multi-CPU machine and a rather slow storage device
* Create a clean chroot as indicated at https://wiki.archlinux.org/title/DeveloperWiki:Building_in_a_clean_chroot
* mkarchroot $CHROOT/root base-devel
* makechrootpkg -c -r $CHROOT

Attached is a patch that fixes the build error.

Technical details:

* When using make -j4 for parallelizing jobs, makepkg runs:

make -C libunrar lib

which runs in parallel:

make clean
make rar.o
make strlist.o
make strfn.o

make clean eventually runs:

@rm -f $(OBJECTS) $(UNRAR_OBJ) $(LIB_OBJ)

If one of the objects was already built before running this rm command, then the object that was just built will be removed. After that, the linker fails to find this object and errors out.

> fails to build from source

Not quite accurate. It's only in some rare circumstances. You should really be fixing the makefiles and sending a patch upstream.

I did contact upstream and they will fix the issue in the makefile in their next release. Closing this issue.
