However the check similarly to tell and seekdir succeeds. However we will generate the following error down the line:
```

Autoconf hasn’t had an update since 2014, and it doesn’t look like it will soon[1]
This updates config.{guess,sub}

It basically does exactly what the config.guess script says:
> It is advised that you download the most up to date version of the config scripts from

It adds support for e.g. `-ios`, which allows to have targets like `aarch64-apple-ios`.

Android doesn’t have telldir/seekdir in bionic

The isse here is that while we try to use `AC_CHECK_FUNCS`, this will generate test code
that tries to link an object and check for linking errors.  However  GNU gold at least version
(binutils-2.25-0666073 2.25.51.20141117) 1.11, considers seekdir/telldir as part of the
default libs. Thus we would actually want to pass `-nodefaultlibs` to the linker. Doing so,
would result in erros due to not finding `-ldl`.

Fixes #91

Define _POSIX_VDISABLE, if not defined.

Bump time upper bound

Fix error message of `createSymbolicLink`.

Consider `ln` (or any other Unix tool):

    $ ln -s file1 file2
    $ ls -l file2
    lrwxrwxrwx 1 niklas niklas 5 Feb  8 03:09 file2 -> file1
    $ ln -s file1 file2
    ln: failed to create symbolic link 'file2': File exists

The file name mentioned in the error ("link2") is the one
that *could not be created*, not the content of the pointer.

`createSymbolicLink` got this wrong so far, it would print

    file1: createSymbolicLink: already exists (File exists)

which is wrong, this file doesn't already exist.

This commit fixes it.

Needed import of sort and updated expected output

...after having convincing myself that the changes in time-1.7 are confined
to parts not used by `unix`

c.f. http://hdiff.luite.com/cgit/time/diff?id=1.7&id2=1.6.0.1

fixes #80

The order in which getEnvironment returns its result is platform dependent. Sort
the output to ensure consistent output across platforms.

Add argument documentation for Env modules

Fixes #76

Fix segfault from inconsistent macro use.

Don't use readdir_r if deprecated

GNU glibc 2.23 and later deprecate `readdir_r` in favour of plain old
`readdir` which in some upcoming POSIX standard is going to required to be
re-entrant.

Eventually we want to drop `readder_r` all together, but want to be
compatible with older unixen which may not have a re-entrant `readdir`.

Solution is to make systems with *known* re-entrant `readir` use that and
use `readdir_r` whereever we have it and don't *know* that `readdir` is
re-entrant.

Fix travis build

`no_stdin` is no longer necessary, and has been removed from the
testsuite driver

This has the side-effect of making two more modules `Safe`-inferred
