Commit 42abeef7e8df ("perf tools: Build syscall table .c header from kernel's syscall_64.tbl") introduces archheaders dependency. It is added to 'prepare', but not added directly to libperf-in.o, causes following error: $ make -C ./tools/perf/ O=/tmp/xxxxx/ /tmp/xxxxx/libperf-in.o JOBS=1 make: Entering directory `/xx/xx/tools/perf' BUILD: Doing 'make -j1' parallel build Auto-detecting system features: ... dwarf: [ on ] ... dwarf_getlocations: [ on ] <SNIP> CC /tmp/xxxxx/util/map.o CC /tmp/xxxxx/util/pstack.o CC /tmp/xxxxx/util/session.o make[3]: *** No rule to make target `/tmp/xxxxx/arch/x86/include/generated/asm/syscalls_64.c', needed by `/tmp/xxxxx/util/syscalltbl.o'.

Add 'prepare' to libperf-in's dependency.
