perl: Enable rebuilds to account for configuration changes

If configure/compile was rerun for perl, changes such as libdir changes
were not being picked up. To fix this we we add "make clean"
functionality, if the makefile is present.

We also in this case need to delete the .so file, else some perl modules
try and load the target arch libraries leading to build failures. I'd
love it if there were a better way to do this and am open to better
proposals but this was the best I could find, not being a perl expert.
