Remove the bulk of the NaCl port.

The NaCl port has not been actively maintained since before the 2.25
release.  The complementary GCC back-end was never contributed to GCC,
and we are given to understand that the current NaCl SDK has switched
to Clang and therefore cannot be used to build glibc anymore, so we
doubt that the port remains useful.

This commit simply removes the sysdeps/arm/nacl and sysdeps/nacl
directories and the abi-tags entry.

	Remove the NaCl port.
	* abi-tags: Remove .*-.*-nacl.* entry.
	* sysdeps/arm/nacl: Remove directory and contents.
	* sysdeps/nacl: Likewise.

-   (struct pthread) as an identifier that is unique at least among all
-   live threads in the process.  So we must synthesize some number to
-   use.  Conveniently, the 'pthread_t' value itself is already unique
-   in exactly this way (because it's the 'struct pthread' pointer).
-
-   The only wrinkle is that 'tid' is a (32-bit) 'int' and its high
-   (sign) bit is used for special purposes, so we must be absolutely
-   sure that we never use a pointer value with the high bit set.  (It
-   also cannot be zero, but zero is never a valid pointer anyway.)
-   The NaCl sandbox models for 32-bit machines limit the address space
-   to less than 3GB (in fact, to 1GB), so it's already impossible that
-   a valid pointer will have its high bit set.  But the NaCl x86-64
-   sandbox model allows a full 4GB of address space, so we cannot
-   assume that an arbitrary pointer value will not have the high bit
-   set.  Conveniently, there are always unused bits in the pointer
-   value for a 'struct pthread', because it is always aligned to at
-   least 32 bits and so the low bits are always zero.  Hence, we can
-   safely avoid the danger of a nonzero high bit just by shifting the
