OS X: Detect implicit link directories on modern toolchains

We detect the implicit link directories for the toolchain by adding a
flag to get verbose output from the compiler front-end while linking the
ABI detection binary.  Newer OS X toolchains based on Clang do not add
the implicit link directories with -L options to their internal
invocation of "ld".  Instead they use a linker that comes with the
toolchain and is already configured with the proper directories.

Add the "-Wl,-v" option to ask "ld" to print its implicit directories.
It displays them in a block such as:

 Library search paths:
	/...

Parse this block to extract the implicit link directories.

While at it, remove the checks introduced by commit efaf335b (Skip
implicit link information on Xcode, 2009-07-23) and commit 5195a664
(Skip implicit link info for multiple OS X archs, 2009-09-22).  Discard
the non-system link directories added by Xcode.  Discard all detected
implicit libraries in the multi-architecture case but keep the
directories.  The directories are still useful without the libraries
just to suppress addition of explicit -L options for them.
