perf tools: Remove LTO compiler options when building perl support 

To avoid breaking the build by mixing files compiled with things coming
from distro specific compiler options for perl with the rest of perf,
i.e. to avoid this:

  `.gnu.debuglto_.debug_macro' referenced in section `.gnu.debuglto_.debug_macro' of /tmp/build/perf/util/scripting-engines/perf-in.o: defined in discarded section `.gnu.debuglto_.debug_macro[wm4.stdcpredef.h.19.8dc41bed5d9037ff9622e015fb5f0ce3]' of /tmp/build/perf/util/scripting-engines/perf-in.o

Noticed on Fedora 33.
