I can confirm the Segmentation fault on RPi3 with your buildroot configuration:

	$ ./host/usr/bin/arm-buildroot-linux-uclibcgnueabihf-gdb /mnt/root/wget /mnt/root/core
Core was generated by `wget http://www.buildroot.org'.
Program terminated with signal SIGSEGV, Segmentation fault.
#0  rpl_gmtime (timep=0x7ebb390c, 
    timep at entry=<error reading variable: DWARF-2 expression error: Loop detected (257).>)
    at localtime-buffer.c:49
49	{
(gdb) where
#0  rpl_gmtime (timep=0x7ebb390c, 
    timep at entry=<error reading variable: DWARF-2 expression error: Loop detected (257).>)
    at localtime-buffer.c:49
#1  0x000487a8 in rpl_gmtime (

#2  0x000487a8 in rpl_gmtime (

    at localtime-buffer.c:50

...and so on (endless recursion)..., maybe by calling rpl_gmtime with
gmtime defined as rpl_gmtime:

build/wget-1.19.5/lib/localtime-buffer.c:

 47 struct tm *
 48 rpl_gmtime (time_t const *timep)
 49 {
 50   struct tm *tm = gmtime (timep);
 51 
 52   if (localtime_buffer_addr == &tm_zero_buffer)
 53     localtime_buffer_addr = tm;
 54 
 55   return tm;
 56 }

build/wget-1.19.5/lib/time.h:

675 # if 0 || 1
676 #  if 1
677 #   if !(defined __cplusplus && defined GNULIB_NAMESPACE)
678 #    undef gmtime
679 #    define gmtime rpl_gmtime
680 #   endif
681 _GL_FUNCDECL_RPL (gmtime, struct tm *, (time_t const *__timer)
682                                        _GL_ARG_NONNULL ((1)));
683 _GL_CXXALIAS_RPL (gmtime, struct tm *, (time_t const *__timer));
684 #  else
685 _GL_CXXALIAS_SYS (gmtime, struct tm *, (time_t const *__timer));
686 #  endif
687 _GL_CXXALIASWARN (gmtime);
688 # endif

Try with musl or glibc until a proper solution is found?

Peter
