Clash in sethostname char const argument

[Pavel Pisa]

Hello Sebastian,

I am starting to test GCC-4.9.2 toolchain with actual RTEMS
and I have noticed that when I use actual Newlib GIT
there is added

#if __BSD_VISIBLE || (defined(_XOPEN_SOURCE) && __XSI_VISIBLE < 500)
int	_EXFUN(sethostname, (const char *, size_t));
#endif

to include/sys/unistd.h

but RTEMS declares these without const which results
in rtems cpukit build error. Please, commit correction
in type to RTEMS.

Best wishes,

               Pavel
