/usr/bin/python may be python3. We should respect PATH to find the python
executable so it can be locally overridden to be python2.

The test always fails when run on non-production devices. Silence the

(cherry picked from commit 157655dc67)
The specific case of finding a DT_RPATH entry is a pretty common harmless
warning. An alternative to this change would be to just add a case to the
switch for DT_RPATH to just silently ignore it, since it's never been
supported and is deprecated anyway.

Well, all except <threads.h> which we have no current plans to implement.
The only thing this turned up is that clang's <float.h> doesn't define
FLT_HAS_SUBNORM/DBL_HAS_SUBNORM/LDBL_HAS_SUBNORM, so for now we assert
that those are missing so that when we get a fixed clang, we notice.
Also the <tgmath.h> is utterly perfunctory, but seems like an appropriate
amount of effort to put in.

Leaving these unimplemented causes linker to have 2 weak undefined
symbols which in turn results in 3 unwanted relocations for arm arch.
Implementing them removes unwanted relocations from resulted dynamic
object

Because there was an accidental ABI breakage in 21, and we can't fix
the past. It seems more useful to refuse to build code that won't work
on any current or future device.

Spotted while adding syncfs(2). I'd previously seen that this file already
had names, but apparently not inspected them. A couple were missing, a
couple (pipe/pipe2) could usefully have a more specific type, and many
hadruntogethercstylenames.

On LP32 mem_unit will be 4096 to allow more than 4GiB in the "ulong"

- Add a default xml file to run if nothing is specified on the command-line.
- Add a way to specify a xml file in suites without having to specify the
full path name.
- Move all of the test xml files into their own directory.
- Add the suites directory for to glibc benchmarks.
- Add a new test for help data.
- Modify the full suite test to verify the default xml is chosen and use
the real full.xml instead of the test one. Delete the test_full.xml.
- Move the property tests to the end of the suite.
- Add skipping of xml comments.
Test: Ran the unit tests and ran the bionic benchmarks.

libc++ actually provides overloads for all the standard C library stuff,
so we just need to handle the POSIX and GNU extensions, of which there
are just two more: memrchr and strcasestr.

On Pixel 2016, there's about 1us overhead for getline versus
fgets. fgetln(3) is worse still because of the intermediate buffering
(though it might actually be better if you were only reading one line
whose length was less than BUFSIZ).
Also use somewhat realistic input for these benchmarks: /dev/zero makes
no sense at all.
