Ian Rogers bd874cd835 perf build: Use the given CC rather than clang in clang builds
The clang block is entered when CC_NO_CLANG has determined that CC is
clang, but it then ignores CC and hard codes $(CLANG), which defaults to
plain "clang". Building with a versioned compiler silently switches
compiler:

  $ make CC=clang-19		# actually builds with "clang"

Worse, the target triple is probed with $(CLANG) too, so on a machine
that only has versioned binaries installed the probe produces nothing
and the build stops:

  $ make CC=clang-19
  *** Specify CROSS_COMPILE or add CLANG_TARGET_FLAGS for x86_64

Use $(CC) in both places. Within the block CC is known to be clang, and
for "make LLVM=1" CC is already $(CLANG), so nothing changes there.

$(CLANG) is left as it is for BPF skeletons, as bpf_skel.mak builds
those with "$(CLANG) --target=bpf" whatever CC happens to be.
