[patch] www/libxul/Makefile syntax error

[John Hein]

There is a syntax error (since 2010/08/08) in www/libxul/Makefile that
is silently ignored.

The effects are that -pthread is not added to EXTRA_DSO_LDOPTS
in storage/build/Makefile.  It may be that the %%PTHREAD_LIBS%%
patch just isn't needed at all, but I haven't verified that.

This patch (below) fixes the syntax error.

It's possible that an alternative is to remove
files/patch-storage_build_Makefile.in and GECKO_PTHREAD_LIBS related
stuff in the Makefile.
