gnulib-tool broken on solaris

[Ben Walton]

Hi All,

I updated my gnulib git repo tonight before patching it into some
source and discovered that gnulib-tool was broken by commit 5b1da95 (I
bisected).  I've verified this breakage on Solaris 8 - 10.

bwalton @ build8x : ~/gnulib
$ ./gnulib-tool --help
./gnulib-tool[814]: syntax error at line 816 : `(' unexpected
--snip--

The attached patch fixes the problem, but I'm not sure if it's the
best solution or fully portable.

HTH.
