These are only used for type checking, so don't bother importing them at
runtime.
Generally add future annotations at the same time, to make sure that
existing uses of these imports don't need to be quoted.
Using future annotations, type annotations become strings at runtime and
don't impact performance. This is not possible to do with T.cast though,
because it is a function argument instead of an annotation.
Quote the type argument everywhere in order to have the same effect as
future annotations. This also allows linters to better detect in some
cases that a given import is typing-only.

added PACKAGE_VENDOR to lld, causing the -v output to start with "Homebrew LLD"
rather than just "LLD". Meson no longer detects it and fails the
test_ld_environment_variable_lld unit test.

Since they will never be used outside of the build directory, they do
not need to literally contain the .o files, and references will be
sufficient.
This covers a major use of object libraries, which is that the static
library would potentially take up a lot of space by including another
copy of every .o file.

The `init__()` method basically existed solely to be overridden by every
derivative class. Better to use it only in the class that needs it.
This fixes several warnings, including missing calls to init because we
skipped ArLinker due to not wanting it... also get rid of a pointless
popen return code saved as pc, which we never checked.
We have a lot of these. Some of them are harmless, if unidiomatic, such
as `if (condition)`, others are potentially dangerous `assert(...)`, as
`assert(condtion)` works as expected, but `assert(condition, message)`
will result in an assertion that never triggers, as what you're actually
asserting is `bool(tuple[2])`, which will always be true.
For an ELF targets, shared_module() builds a module with SONAME field
(using -Wl,-soname argument). This is wrong: only the shared_library()
needs SONAME, while shared_module() does not. Moreover, tools such as
debian's dpkg-shlibdeps use presence of SONAME field as an indicator
that this is shared library as opposed to shared module (e.g., for the
module it is okay to have unresolved symbols which are imported from
the executable which loads the module, while a library should have all
symbols resolved).
This was in fact already the behavior on Darwin; extend it to ELF
targets as well.
