More specific, please re-apply this patch [1] and extend it for sparc64
as well:

This patch was dropped when gudev was removed from systemd upstream
assuming that linking with gold would affect gudev only. However,
it affects linking against libsystemd and libudev in general,
for example usbutils [2]:

/bin/bash ../libtool  --tag=CC   --mode=link gcc  -Os -Wall -g -O2
-fstack-protector-strong -Wformat -Werror=format-security
-I/usr/include/libusb-1.0   -Wl,-z,relro -o usbhid-dump usbhid-dump.o
../lib/libuhd.la -lusb-1.0
libtool: link: gcc -Os -Wall -g -O2 -fstack-protector-strong -Wformat
-Werror=format-security -I/usr/include/libusb-1.0 -Wl,-z -Wl,relro -o
usbhid-dump usbhid-dump.o  ../lib/.libs/libuhd.a -lusb-1.0
/usr/bin/ld: //lib/sparc64-linux-gnu/libudev.so.1: Only registers
%g[2367] can be declared using STT_REGISTER
//lib/sparc64-linux-gnu/libudev.so.1: error adding symbols: No such file

collect2: error: ld returned 1 exit status

Thanks,

Adrian
