Fix tsan abort for lake of __libc_auxv initialization.
If tsan is used, the following callchain can happen:
__libc_preinit() -> __libc_init_globals() ->
__libc_init_vdso() -> strcmp() -> __tsan_init()
-> sysconf(_SC_PAGE_SIZE) -> getauxval().
But __libc_auxv is initialized in __libc_init_common(),
after __libc_init_globals(). One simple way to fix
this is to initialize __libc_auxv at __libc_init_globals().
