bug#23751: version 1.8: errors in build and testsuite

[Helmut Karlowski]

Build-error:

If configure finds that asm does not work it does not define ASMV in  
lib/config.h so the c-versions of some functions (e.g. longest_match)  
shall be used. But tailor.h says in line 187:

#if defined(ATARI) || defined(atarist)
#  define ASMV

and the build fails because match.o is not in gl_LIBOBJS. The reason for  
the asm-failure is not related.

testsuite: help-version uses

  if type ${prog}_setup > /dev/null 2>&1; then
    ${prog}_setup
  fi

in line 261, but is executed by #!/bin/sh, which does not have a  
type-builtin, and the test fails because of this (#!/bin/bash would work).
