From: Sergei Trofimovich <slyfox at gentoo.org>
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.
The change adds m4 quoting around it.
On `autoconf-2.69` there is no `./configure` code
generation change. On `autoconf-2.69c` `./configure`
gets to the finish.
