tools: move sstrip to the binary utilities menu

sstrip is now alone in its 'tools' menu, and we will probably never gain
any other 'tool'. Besides, sstrip is just strip, but a little bit more
agressive, so it deserves going to the 'binary utilities' menu.
     1 Original patch from H.J. Lu, as reported there:
     2 http://www.nabble.com/PATCH:-Use-short-for-fnstsw-td14775171.html
     3 
     4 fnstsw stores 16bit into %ax. The upper 16bit of %eax is unchanged.
     5 The new assembler (binutils-2.18.50.0.4 and up) will disallow "fnstsw %eax".
