[PATCH 0/4] Fix gdb.rocm/simple.exp on hosts without ROCm

[Lancelot SIX <lancelot.six@amd.com>]

Hi,

Tom De Vries reported that the gdb.rocm/simple.exp test (recently introduced
with the AMDGPU support) can fails[1].  I can reproduce this problem
(and variations of it) on systems where GDB is not build with the AMDGPU
support, or which do not have the ROCm stack installed.

This series fixes this test failure by only running the test if:
- GDB is build with AMDGPU support (patch 1 and 3)
- if the hipcc compiler is installed and can compile a simple HIP
  program which offloads a task to an AMDGPU device (patch 4).

Patch 3 is a small refactoring to use "require" in gdb.rocm/*.exp.

All feedbacks are welcome.

Best,
Lancelot.
