Since Linux-firmware's commit 9cfefbd7fbda ("Remove duplicate symlinks")
symlinks aren't distributed anymore. They are rather created at
installation time by a script provided in the project, copy-firmware.sh.
The description of the symlinks is done in the WHENCE file. Since the
bump to version 20200122, in commit 48cc1a89ae, installation for many
firmwares was broken as Buildroot tried to install missing symlinks from
Linux-firmware.
The fix is not only to remove now missing symlinks, but to add logic to
create those symlinks as kernel modules will depend on them. The
solution taken by this patch is to create dynamically symlinks based on
their description in the WHENCE file *and* only if the file they'll
point to was installed in the target directory.

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on Freenode IRC.
