Avoid error message during "make check"

[Bruno Haible]

On FreeBSD 12/x86_64, building and installing poke 0.91 succeeds.

Preparations:
  # pkg install boehm-gc readline json-c tk87 libtextstyle dejagnu

Configuration:
  $ BDW_GC_CFLAGS=""; BDW_GC_LIBS="-lgc"; export BDW_GC_CFLAGS BDW_GC_LIBS
  $ ./configure CPPFLAGS="-I/usr/local/include -Wall" \
                LDFLAGS="-L/usr/local/lib"

When doing 'make check' (with 'make', not 'gmake'), there is an error message:

$ make check
...
                === poke Summary ===

# of expected passes            5164
# of unsupported tests          3
/bin/sh: ../inputrc: Permission denied
*** Error code 126

Stop.
make[3]: stopped in /usr/home/bruno/poke-0.91/build/testsuite

The reference $(RM) to an undefined make variable expands to empty.

The attached proposed patch fixes it.
