stage2: add --sysroot link option
...
This feature is necessary for cross-compiling code that dynamically
links system libraries, at least with the current feature set of lld.

Add fat/universal dylib support to zig ld
...
With this change zig ld can link with dynamic libraries
contained within a fat/universal file that had multiple
seperate binaries embedded within it for multi-arch
support (in macOS).
Whilst zig can still only create single-architecture
executables - the ability to link with fat libraries is
useful for cases where they are the easiest (or only)
option to link against.

zld: merge Stub with Dylib struct
...
After giving it more thought, it doesn't make sense to separate
the two structurally. Instead, there should be two constructors
for a Dylib struct: one from binary file, and the other from a stub
file. This cleans up a lot of code and opens the way for recursive
parsing of re-exports from a dylib which are a hard requirement for
native feel when linking frameworks.

zld: introduce Stub.zig which represents parsed stub file
...
Instead of trying to fit a stub file into the frame of a Dylib struct,
I think it makes more sense to keep them as separate entities with
possibly shared interface (which would be added in the future).
This cleaned up a lot of logic in Dylib as well as Stub. Also, while
here I've made creating actual *Symbols lazy in the sense Dylib and
Stub only store hash maps of symbol names that they expose but we
defer create and referencing given dylib/stub until link time when
a symbol is actually referenced. This should reduce memory usage
and speed things up a bit.
