Subject: [PATCH] configure.ac: fix a bashism

There's one instance of VAR+=" value" in the configure script, but
that only works in bash. With dash, for example, it results in

  checking whether gmp version is at least 40000... yes
  ./configure: 17953: REQUIRED_FLAGS+= : not found

We change it to a VAR="${VAR} value" instead.
