perf build: Don't use -ffat-lto-objects in the python feature test when building with clang-13
commit 3a8a0475861a443f02e3a9b57d044fe2a0a99291 upstream.
Using -ffat-lto-objects in the python feature test when building with
clang-13 results in:
clang-13: error: optimization flag '-ffat-lto-objects' is not supported [-Werror,-Wignored-optimization-argument]
error: command '/usr/sbin/clang' failed with exit code 1
cp: cannot stat '/tmp/build/perf/python_ext_build/lib/perf*.so': No such file or directory
make[2]: *** [Makefile.perf:639: /tmp/build/perf/python/perf.so] Error 1
Noticed when building on a docker.io/library/archlinux:base container.
