binutils/sstrip: remove

sstrip has been obsoleted for a while now, as it's still broken
for some archs, and there seems to be no incentive to fix it
upstream. Besides, the space gained with sstrip is marginal at
best.

-        sstrip is now deprecated in crosstool-NG, as it has a few

-        does not build on non-ELF hosts (eg. mingw32, MacOS-X...).
