Auto-generate NOTICE files for all the directories, and for each one
individually rather than mixing libc and libm together.

The benchmark calls __cxa_atexit 100000 times, then either exits early
without calling the destructors (_Exit) or exits normally, calling them
(exit).

The benchmark creates a set of DSOs that mimic the work involved in
loading the current version of libandroid_servers.so. The synthetic
benchmark has roughly the same number of libraries with roughly the same
relocations.
Currently, on a local aosp_walleye build that includes recent performance
improvements (including the Neon-based CL
I3983bca1dddc9241bb70290ad3651d895f046660), using the "performance"
governor, the benchmark reports these scores:

This reverts commit 3bf27c86d1327a5a66bf06af07027c4f1a37d358.
Disable the 32-bit glibc target. We're not interested in benchmarking that
target, and the bench_noop_nostl executable doesn't build when ASAN is
turned on, because the libclang_rt.asan_cxx-i386.a lib contains
ubsan_type_hash_itanium.cc.o, which needs __dynamic_cast and various
STL typeinfo variables. The equivalent libclang_rt.asan_cxx-x86_64.a
lib doesn't have ubsan_type_hash_itanium.cc.o in it.

Specifically, test the wall-clock time for running:
* a C program that does nothing (i.e. no STL)
* a C++ program that does nothing
* a statically-linked C++ program
* toybox true (in /system/bin and /vendor/bin)
* mksh -c true (in /system/bin and /vendor/bin)
Test: bionic-spawn-benchmarks
