This reverts commitd79a27195a. According to the commit description, this ld-option test was added for the gold linker at that time. Commit75959d44f9("kbuild: Fail if gold linker is detected") gave up the gold linker support after all. I tested the BFD linker from binutils 2.23 and LLD from LLVM 11.0.0. Both of them support the -X option.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
