Archives require a symbol table on Solaris, even if empty.
On Solaris ld (and some other tools that use the underlying utility
libraries, such as elfdump) chokes on an archive library that has no
symbol table. The Solaris tools always create one, even if it's empty.
That bug has been fixed in the latest development line, and can
probably be backported to a supported release, but it would be nice if
LLVM's archiver could emit the empty symbol table, too.
Patch by Danek Duvall!
