tried below fix, that is a partial revert of klibc
6fbd8fafdcc793135988733996d72b0298afe934
see git://git.kernel.org/pub/scm/libs/klibc/klibc.git
with belows fix klibc compiles fine on sparc with newer gcc,
but segfaults:
titan:~# strace -vfF /usr/lib/klibc/bin/fstype
execve("/usr/lib/klibc/bin/fstype", ["/usr/lib/klibc/bin/fstype"],
["SHELL=/bin/bash", "TERM=xterm", "SSH_CLIENT=[myip] 39403"...,
"SSH_TTY=/dev/pts/0", "USER=root",
"LS_COLORS=no=00:fi=00:di=01;34:l"...,
"PATH=/usr/local/sbin:/usr/local/"..., "MAIL=/var/mail/root",
"PWD=/root", "LANG=en_US.UTF-8", "PS1=\\h:\\w\\$ ", "HOME=/root",
"SHLVL=2", "LS_OPTIONS=--color=auto", "LOGNAME=root",
"SSH_CONNECTION=[myip] 3"..., "_=/usr/bin/strace", "OLDPWD=/"]) = 0

thanks for looking at it.

use our own clzdi on sparc instead the one of libgcc
