[PATCH 0/5] selftests: target selection fixes for cross and LLVM builds

[Sasha Levin <sashal@kernel.org>]

A few suites select their tests from the build host instead of the
target, or depend on the host C library in ways that break cross
builds. This series fixes the ones found while building the selftests
for several architectures:

 - prctl and the Intel thermal suites build nothing when CROSS_COMPILE
   is set, even for x86, and prctl restricts two generic tests to x86.

 - set-anon-vma-name-test fails instead of skipping on kernels built
   without CONFIG_ANON_VMA_NAME.

 - kexec only recognizes the ppc64le spelling of PowerPC and decides
   about the x86-64 jump test from the build host.

 - size links a custom _start against the static C library, which
   fails on ARM with clang and on LoongArch; it now uses nolibc.

The patches are independent of each other.

Sasha Levin (5):
  selftests/prctl: build generated tests for the target architecture
  selftests/prctl: skip the anonymous VMA naming test when unsupported
  selftests/thermal: allow cross builds of the Intel tests
  selftests/kexec: select tests using the target compiler
  selftests/size: use nolibc startup and syscall wrappers
