clisp testing on linux

Yes, I am on Linux amd64 using
make -f Makefile t l=clisp t=test-encodings.script

On Debian, using GNU CLISP 2.49.92 (2018-02-18) everything works fine.
On NixOS, using GNU CLISP 2.49.60+ (2017-06-25) I get the error
POSIX:COPY-FILE: illegal keyword/value pair :METHOD, :RENAME in argument list.
The allowed keywords are NIL

That's weird, because I've been using these arguments to copy-file
since the very first ASDF 3 prerelease (2.27) in 2013 and never had
this issue before. I'll blame the NixOS build script for failing to
configure clisp properly.
