RM is one of the variables that should be pre-initialized by Make, and
AFAIK should be used to increase portability (well, it's likely not
important for QEMU since we require a posix-shell like built environment
anyway).

According to the info page of Make, chapter "10.3 Variables Used by
Implicit Rules":

`RM'
     Command to remove a file; default `rm -f'.

I've also checked it again and "make clean" works fine here (using GNU
Make 3.82). Which version of Make (and Linux distro) are you using?

Anyway, maybe I also simply missed something, so I'm certainly also fine
with the patch to revert it to "rm -f".
