Makefile change needed to link on Raspbian 11

[mk2987]

While amouse builds fine on my x86 Linux machine (Arch Linux), it was failing at link time on my Raspberry Pi:

$ make

To fix this, we need to add the --no-as-needed flag to CFLAGS in the Makefile, or move -levdev to be after the object file names in the final build command. Apparently the linker on Raspbian 11 has --as-needed set by default (see the man page for ld for details on why this causes problems when -levdev is before the object files)

I had a look over this and while I can't easily directly test this at the moment, I've changed the order of parameters for the final linking so that the libraries are included last after the objects. That appears to be the most compatible way to handle this issue as "--no-as-needed" is not a fully standard flag from what I'm seeing.

This change is in the current cba115f commit of the dev branch.
