perf callchains: Disable unwind libraries when libelf isn't found
I.e. do the same as when NO_LIBELF is explicitely passed in the 'make' command line, fixing this:
Auto-detecting system features: ... dwarf: [ OFF ] ... glibc: [ on ] ... gtk2: [ OFF ] ... libaudit: [ OFF ] ... libbfd: [ OFF ] ... libelf: [ OFF ] ... libunwind: [ OFF ] ... libdw-dwarf-unwind: [ OFF ] ... DWARF post unwind library: libdw <SNIP> CC /tmp/build/perf/util/symbol-minimal.o CC /tmp/build/perf/util/unwind-libdw.o arch/x86/util/unwind-libdw.c:1:30: fatal error: elfutils/libdwfl.h: No such file or directory compilation terminated. CC /tmp/build/perf/tests/keep-tracking.o util/unwind-libdw.c:2:28: fatal error: elfutils/libdw.h: No such file or directory compilation terminated.
