Sounds familiar.  I recall I dealt with this problem some time ago.  In
short, it was introduced by one of the dependencies of X server
(libXfont):

  https://cgit.freedesktop.org/xorg/lib/libXfont/commit/?id=7b377456f95d2ec3ead40f4fb74ea620191f88c8

X server allowed to use symlinks for fonts before that commit,
but not anymore.

I fixed it on my side simply by making 'my-xorg-server' package
that uses a "fixed" version of libxfont (that supports symlinks).

If anyone is interested, I also wrote a descriptive commit message here:

  https://notabug.org/alezost/guix-config/commit/161d5e2e36e53c0d9c46181e10e1595e607748dd
