Can define custom linker flags.

project('linker script', 'c')
Allow link_depends to take strings, Files or generated objects. Closes #1172 Currently only strings can be passed to the link_depends argument of executable and *library, which solves many cases, but not every one. This patch allows generated sources and Files to be passed as well. On the implementation side, it uses a helper method to keep the more complex logic separated from the __init__ method. This also requires that Targets set their link_depends paths as Files, and the backend is responsible for converting to strings when it wants them. This adds tests for the following cases: - Using a file in a subdir - Using a configure_file as an input - Using a custom_target as an input It does not support using a generator as an input, since currently that would require calling the generator twice, once for the -Wl argument, and once for the link_depends. Also updates the docs.

# Static map file
Added a link_depends keyword for build targets.

The mass flags -> args renaming for consistency.
