maintainer-makefile: quoting

[Simon Josefsson]

I got this error from syntax-check:

address@hidden:~/src/libidn$ make sc_vulnerable_makefile_CVE-2012-3386
vulnerable_makefile_CVE-2012-3386
/bin/sh: 2: Syntax error: "(" unexpected
make: *** [sc_vulnerable_makefile_CVE-2012-3386] Fel 2
address@hidden:~/src/libidn$ 

The patch below appears to fix it.  This is on a system with dash as
/bin/sh.  Thoughts?
