Note: fully static linking is not supported by libsanitizer at all and I don't
think it will. 
Reason: on linux asan uses "dlsym(RTLD_NEXT, ...)" and on Mac it uses 
(will soon use) function inerposition. 
Neither works for fully static binaries, afaict.

Then we should issue an error if -static is used with -faddress-sanitizer.

For -static one could perhaps use --wrap ld option to wrap various symbols, but
we'd need special libasan_static.a for that.  Not worth it.

So we need %{static:%e-fsanitize=address requires dynamic linking} or similar
in LIBASAN_SPEC.
