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.
