debug/gdb: update the version strings

Almost all versions have been renamed, but the gdb folks did not

     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".
