So what need to happen?

rpcdebug tool is being installed in the nfs-utils.spec %install section:

install -s -m 755 tools/rpcdebug/rpcdebug $RPM_BUILD_ROOT/usr/sbin

The '-s' option causes the binary to be stripped of debugging information during the install. Please remove the '-s' option there.

and do code review to check the '-s' option had been removed in the nfs-utils.spec %install section:
install -m 755 tools/rpcdebug/rpcdebug $RPM_BUILD_ROOT/usr/sbin
