Libtool concludes that the linker doesn't support shared libraries,
unless this flag is listed in the output of --help.

When integrating PDB output in mingw targeting build systems, it
might be a lot of extra work to specify unique file names for
the pdb output. Therefore allow omitting the actual file name
and let it implicitly be the same name as the linker output, with
a pdb extension.
As the current form of the pdb option takes a separate parameter value,
e.g. "-pdb out.pdb", it is impractical to leave out the parameter value.
Therefore, introduce a second syntax for the option, with an equals
sign, like -pdb=out.pdb, where the value easily can be omitted.
The form -pdb= for requesting pdb files with an implicit name should
work fine, even though it looks a bit unconventional in that form.

This is necessary for handling defaultlib directives embedded in
object files, unless they use an absolute path.

In this mode, we retain the symbol table, but skip the actual debug
information.

This allows producing pdb debug info. This is an LLD specific option
since GCC and GNU binutils doesn't support the PDB file format.

The linker refuses using -dynamicbase:no on these architectures.
Stop passing -dynamicbase (which just reinforces the lld-link
default) for simplicity.

GNU ld doesn't seem to support --icf at all, but this was suggested
in D39885, and GNU gold seems to support it.

All of these are disabled by default in GNU ld, but enabled by default
in lld.
Disable dynamicbase by default since it potentially could cause
compatibility issues, but just ignore the others since the lld
default should be fine for most concievable cases.

In GNU ld, this option is only available on i386, not on x86_64
(where it's enabled by default with no option to disable it either).

GNU ld manual says that multi-letter long option can be prefixed with
either -- or -. Therefore, we should accept not only --subsystem but
also -subsystem, for example.
There is one exception. If an option starts with "o", it should only be
prefixed with -- to avoid ambiguity with -o<filename> option.

In MinGW configurations (GCC, or clang with a *-windows-gnu target),
the -export directives in the object file contains the undecorated
symbol name, while it is decorated in MSVC configurations. (On the
command line, link.exe takes an undecorated symbol name for the
-export argument though.)

On i386, the --entry parameter to GNU ld is supposed to be a decorated
symbol name, while it is an undecorated name in link.exe.
