[bug#48541] [PATCH] gnu: Fix build for ldc.

[Roel Janssen <roel@gnu.org>]

Dear Guix,

I looked into why our LDC package fails to build, and it seems that all 
tests that make use of "ptrace" fail because the build environment 
doesn't allow it.
So I disabled these tests by removing the relevant files, and completed 
a successful build.

If there is a way to provide the build environment with the ability to 
use ptrace, and if that is preferred to removing tests, then please let 
me know so I can prepare another patch.

Kind regards,
Roel Janssen
