This one is puzzling. I could not reproduce it on my build machine
(Fedora 25, gcc 6.3.1).

The build of the host variant of skalibs fails at configuration time as
follow:

```
Checking whether system has timer_create()...
  ... yes, with -lrt
  Checking system endianness...
  ./configure: unable to determine endianness
```

At this step, ./configure tries to compile two programs to determine
endianness (src/sysdeps/trybigendian.c and src/sysdeps/trylittleendian.c).
Both test some compiler macros related to endianness. Example, for big
endian:

```
#if defined(__BYTE_ORDER) && (__BYTE_ORDER == __BIG_ENDIAN) ||?        \
?       defined(__BYTE_ORDER__) && (__BYTE_ORDER__  ==
__ORDER_BIG_ENDIAN__) || \
?       defined(__BIG_ENDIAN) ||?       ?       ?       ?              \
?       defined(__ARMEB__) ||?  ?       ?       ?       ?              \
?       defined(__THUMBEB__) ||?        ?       ?       ?              \
?       defined(__AARCH64EB__) ||?      ?       ?       ?              \
?       defined(_MIPSEB) || defined(__MIPSEB) || defined(__MIPSEB__)
#define YEAH
#else
#error "not big endian"
#endif
```

So the failure means that both programs failed to compile. Which
version of GCC is used on the autobuild machine?

Best regards,

gcc 4.4.5 is used. It fails with:

Checking system endianness...
src/sysdeps/trybigendian.c:10:2: error: #error "not big endian"
src/sysdeps/trylittleendian.c:10:2: error: #error "not little endian"
./configure: unable to determine endianness

From a quick look, I don't see anything to determine the endianness of
the platform. Perhaps simply augment the test case with the assumption
that x86 and x86-64 are little endian?

Thanks!
