[git commit nptl] sh: Align sh clone implementation with glibc

[Carmelo Amoroso]

commit: http://git.uclibc.org/uClibc/commit/?id=defe0a2ced5d3234fb32ceba5fb8bc72f348b859
branch: http://git.uclibc.org/uClibc/commit/?id=refs/heads/nptl

Align sh clone implementation with glibc one that incorporated
time ago a patch provided by me slightly modified.
The glibc code indeed avoids to load the r3 register if the 2nd
function argument is NULL (r5). No functional change.
