debug/gdb: staticaly link to ncurses for the native gdb

Staticaly link the native gdb (the one that runs on the target,
not the cross one that runs on the host) to ncurses.
     1 Original patch from gentoo: gentoo/src/patchsets/gcc/4.3.0/gentoo/53_all_gcc4-superh-default-multilib.patch
     2 The gcc-3.x toolchains would contain all the targets by default.  With gcc-4,
     3 you have to actually list out the multilibs you want or you will end up with
     4 just one when using targets like 'sh4-linux-gnu'.
     5 
     6 The resulting toolchain can't even build a kernel as the kernel needs to build
     7 with the nofpu flag to be sure that no fpu ops are generated.
     8 
     9 Here we restore the gcc-3.x behavior; the additional overhead of building all
    10 of these multilibs by default is negligible.
