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 (

at localtime-buffer.c:50
#2 0x000487a8 in rpl_gmtime (

#3 0x000487a8 in rpl_gmtime (
timep=<error reading variable: DWARF-2 expression error: Loop detected (257).>)
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?
