Previously, we had dependency making pretty much hard coded in the
build file templates, with a bit of an exception for Unix family
platforms, where we had different cases depending on what dependency
making program was found.
With the Embarcadero C++ builder, a separate scheme appeared, with a
different logic.
This change merges the two, and introduces two config target
attributes:
makedepcmd The program to use, where this is relevant.
This replaces the earlier configuration
attribute 'makedepprog'.
makedep_scheme This is a keyword that can be used by build
files templates to produce different sorts of
commands, but most importantly, to pass as
argument to util/add-depend.pl, which uses
this keyword as a "producer" for the
dependency lines.
If the config target doesn't define the 'makedep_scheme' attribute,
Configure tries to figure it out by looking for GCC compatible
compilers or for the 'makedepend' command.

The modified way to generate .d files had an unfortunate side effect,
that it outputs the whole preprocessed file and not just the dependency
lines, at least with MSVC's cl. That gave util/add-depends.pl a whole
lot more to read through, which impacts greatly on the performance of
dependency treatment.
We modify the process by adding a config target attribute 'make_depend',
which can be any suitable command for generating such lines. All it
needs is to also accept C flags and macro definitions.
Fixes#14994

MSVC's `link.exe` automatically finds `__cdecl` C functions (which are
decorated with a leading underscore by the compiler) when they are
mentioned in a `.def` file without the leading underscore. This is an
[under-documented feature][1] of MSVC's `link.exe`. C++Builder's
`ilink32.exe` doesn't do this, and thus needs the name-translation in
the `.def` file. Then `implib.exe` needs to be told to re-add it.
(The Clang-based `bcc32c.exe` doesn't implement the [`-vu` or `-u-`][2]
options to skip adding the leading underscore to `__cdecl` C function
names, so this is the only way to have things work with non-underscored
export names in the DLLs.)

Also silence linker warnings on duplicate symbols and ensure that error-
case cleanup in link rules work in C++Builder's `make.exe`.
