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?
