[PATCH v3 04/11] accel/tcg: Add stub for probe_access()

From: Philippe Mathieu-Daudé
Subject: [PATCH v3 04/11] accel/tcg: Add stub for probe_access()
Date: Thu, 21 May 2020 21:59:04 +0200

From: Philippe Mathieu-Daudé <address@hidden>

The TCG helpers where added in b92e5a22ec3 in softmmu_template.h.
probe_write() was added in there in 3b4afc9e75a to be moved out
to accel/tcg/cputlb.c in 3b08f0a9254, and was later refactored
as probe_access() in c25c283df0f.
Since it is a TCG specific helper, add a stub to avoid failures
when building without TCG, such:

  target/arm/helper.o: In function `probe_read':
  include/exec/exec-all.h:362: undefined reference to `probe_access'
