debug/gdb: we don't care if the host tic is shared or static

Because we need our own host tic, we have to build it; and we do build
it statically for now.

But as MacOS/Darwin/Whatever-you-call-it does not support static linking
(what a shame!), it fails.

Anyway, we don't really care it being shared, in the end.

     4 Original patch from gentoo: gentoo/src/patchsets/gcc/4.3.1/gentoo/53_all_gcc4-superh-default-multilib.patch
     5 The gcc-3.x toolchains would contain all the targets by default.  With gcc-4,
     6 you have to actually list out the multilibs you want or you will end up with
     7 just one when using targets like 'sh4-linux-gnu'.
     8 
     9 The resulting toolchain can't even build a kernel as the kernel needs to build
    10 with the nofpu flag to be sure that no fpu ops are generated.
    11 
    12 Here we restore the gcc-3.x behavior; the additional overhead of building all
    13 of these multilibs by default is negligible.
