aclocal.m4: Fix compatibility with upcoming autoconf-2.70.

Browse source 
Under autoconf 2.69c (beta) `./configure` fails as:

```
./configure
...
checking for msgfmt... msgfmt
./configure: line 7441: syntax error near unexpected token `newline'
./configure: line 7441: `    '''
```

This happens due to underquoting of a snippet
argument for `AS_VAR_SET_IF` call.
