Commit28b1a824a4("arm64: vdso: Substitute gettimeofday() with C implementation") introduced an unused 'VDSO_LDFLAGS' variable to the vdso Makefile, suggesting that we should be passing '-Bsymbolic' to the linker, as we do when linking the compat vDSO. Although it's not strictly necessary to pass this flag, it would be required if we were to add any internal references to the exported symbols. It's also consistent with how we link the compat vdso so, since there's no real downside from passing it, add '-Bsymbolic' to the ldflags for the native vDSO.

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.
