bug#49307: clisp: build failure: failing tests

[Christopher Howard]

Attempting to build clisp from source results in these test failures:

```

(echo *.erg | grep '*' >/dev/null) || (echo "Test failed:" ; ls -l *erg; echo "To see which tests failed, type" ; echo "    cat "`pwd`"/*.erg" ; exit 1)

Test failed:

-rw-r--r-- 1 nixbld nixbld 188 Jun 30 21:15 path.erg

-rw-r--r-- 1 nixbld nixbld 658 Jun 30 21:15 streams.erg

-rw-r--r-- 1 nixbld nixbld 500 Jun 30 21:15 streamslong.erg

To see which tests failed, type

    cat /tmp/guix-build-clisp-2.49-92.drv-0/source/src/tests/*.erg

make[2]: *** [Makefile:34: compare] Error 1

make[2]: Leaving directory '/tmp/guix-build-clisp-2.49-92.drv-0/source/src/tests'

make[1]: *** [Makefile:2216: check-tests] Error 2

make[1]: Leaving directory '/tmp/guix-build-clisp-2.49-92.drv-0/source/src'

make: *** [Makefile:28: check] Error 2

Test suite failed, dumping logs.

command "make" "check" "-j" "1" failed with status 2

```

I did a pull about one or two hours ago.
