[UNIKRAFT/MUSL PATCH 6/7] Prevent syscall shim layer libc wrapper generation

[gaulthier.gain@xxxxxxxxx]

From: Gaulthier Gain <gaulthier.gain@xxxxxxxxx>

The musl libc provides its own wrappers around syscalls, which we
prefer to the shim-layer-generated ones as they often do additional
bookkeeping. And we can not have both as it would lead to conflicts.
