Untested fix.  If -static-libasan is missing, it just moves -lasan early on ld
command line (before %o, i.e. user input arguments), as we error out on -static
and user -Bstatic would go after it, I think it is fine this way.  For
-static-libasan, we don't pass -lasan at all for -shared (we don't want many
(partial) copies of libasan.a in various shared libraries plus executable),
and just for executable link with -Bstatic --whole-archive -lasan
--no-whole-archive -Bdynamic early on the command line.
