[PATCH RESEND 0/3] 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:

 - 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 and apply on
mm-nonmm-unstable.

Since the original posting:

 - "selftests/prctl: build generated tests for the target architecture"
   is dropped. "selftests/prctl: select the tests by ARCH alone" in
   mm-nonmm-unstable replaces it.

 - "selftests/thermal: allow cross builds of the Intel tests" is dropped,
   it went in through the thermal tree as ff4194e54f84.

 - The size patch has Thomas's Reviewed-by.
