* changes:
Use LOCAL_LDFLAGS_64 instead of enumerating 64-bit architectures
Fix typo in cpu variant makefile depenendency for arm64
Remove libc_static_common_src_files
Share LP32 makefile settings between arches
libc_static_common_src_files is never set after
c3f114037d, remove the remaining
references to it.

Add <var>_32 to patch-up-arch-specific-flags, and move the LP32
cruft varaibles from the 32-bit arch specific makefiles into the
top level Android.mk.

This is now necessary to build .dat files that are useable for ICU4J as
well, and will need to be used for any future updates of the .dat file:

for LP64 these will be hidden. for LP32 we were cowards and left
them all public for compatibility (though i don't think we ever
dremeled to see whether it was needed). we don't have an easy
way to recognize additions, though, so we can't prevent adding
new turds.
Add a mechanism to prevent the adding of new turds, and use that
mechanism on the fchmod/fchmodat system calls.

If we lose the #ifndef, the compiler will tell us if the definitions
of SEEK_SET and friends ever get out of sync.

Many libc functions have an option to not follow symbolic
links. This is useful to avoid security sensitive code
from inadvertantly following attacker supplied symlinks
and taking inappropriate action on files it shouldn't.
For example, open() has O_NOFOLLOW, chown() has
lchown(), stat() has lstat(), etc.
There is no such equivalent function for chmod(), such as lchmod().
To address this, POSIX introduced fchmodat(AT_SYMLINK_NOFOLLOW),
which is intended to provide a way to perform a chmod operation
which doesn't follow symlinks.
Currently, the Linux kernel doesn't implement AT_SYMLINK_NOFOLLOW.
In GLIBC, attempting to use the AT_SYMLINK_NOFOLLOW flag causes
fchmodat to return ENOTSUP. Details are in "man fchmodat".
Bionic currently differs from GLIBC in that AT_SYMLINK_NOFOLLOW
is silently ignored and treated as if the flag wasn't present.
This patch provides a userspace implementation of
AT_SYMLINK_NOFOLLOW for bionic. Using open(O_PATH | O_NOFOLLOW),
we can provide a way to atomically change the permissions on
files without worrying about race conditions.
As part of this change, we add support for fchmod on O_PATH
file descriptors, because it's relatively straight forward
and could be useful in the future.
The basic idea behind this implementation comes from
https://sourceware.org/bugzilla/show_bug.cgi?id=14578 , specifically
comment #10.

Don't send the trailing NUL bytes to the logger, call strlen if we already
know the length, or cast more specifically than we need to.

We build one too many times. Creating a missing directory
is sufficient.
The tz2icu needs some files in the CWD. Added symlinks.

All these inlines were turned in to out of line definitions in L.
This brings us a step closer to being able to just use the current
bionic headers for the NDK, rather than having many old versions of
them.

The kernel version of the stat structure is used during the syscalls. After the syscall,
the kernel stat structure is converted to match the generic one. Eventually we would like
the generic stat structure and related syscalls be added to MIPS64 kernel, removing the
thunks added to AOSP.

Move various mips-only things into the arch-mips directory. As soon as mips
writes assembler replacements, we can remove these.

Interestingly, this mostly involves cleaning up our implementation of
various <string.h> functions.
