[m-dev.] For review: "Absolutify" relative paths for shared libraries

[Warwick Harvey]

Estimated hours taken: 1

scripts/ml.in:
	If a shared library directory given to `ml' is relative, turn it
	into an absolute path by prepending the current directory.  Also
	add an option `--leave-shared-lib-dirs-relative' to `ml' which
	turns off this behaviour, in case the user does actually want a
	relative path.
