New 3.8 clang/llvm can compile TLS code now.
* For x86_64, still disable clang due to f128 bug.
* For b/25643775, arm and arm64, disable clang in unit tests.
* Fix thread_local_test.cpp to compile with clang and
limit gcc workaround only to arm and aarch64.

Root cause:
If start_routine thread exits before pthread_gettid_np is invokded, the "tid" field
will be cleared so that pthread_gettid_np will get "0" (which is cleared by kernel,
due to the flag "CLONE_CHILD_CLEARTID" is set while calling clone system call inside
pthread_create).
Proposed patch:
Use a mutex to guarantee pthread_gettid_np will be invoked and returned before the
start_routine exits

The current comment implies that we only strip sensitive
environment variables on executing a setuid program. This is
true but incomplete. The AT_SECURE flag is set whenever a
security transition occurs, such as executing a setuid program,
SELinux security transition, executing a file with file capabilities,
etc...
Fixup the comments.

The mremap definition was incorrect (unsigned long instead of int) and
it was missing the optional new_address parameter.

Including glibc's <libgen.h> will result in the user getting the POSIX
version of basename always, regardless of when it is included relative
to <string.h>. Prior to this patch, our implementation would result in
the one that's included first winning.

The original comment implied that Android 32 bit was the only one
using a bad time_t, but it turns out 32 bit glibc has the same time_t
as Android. Update the comment to reflect this reality.

_signal was static in 64 bit, and hidden on 32 bit. There is no
reason to have this distinction, so make it hidden in all cases.
