[PATCH] configure: set platform variables also when `uname` is unrecognized

[Tomi Ollila]

Since commit

124a67e96ecab5495c0f17b6875d53dfd67ff137: configure: add set -u

all variables must be set before their expansion are attempted. These
2 variables: "platform" and "linker_resolves_library_dependencies" were
not given value in the final 'else' branch when platform check failed
due to unrecognized kernel name (output of `uname`). Now those two are
given reasonable non-empty values.
---

Unfortunately I did not catch these 2 while doing 124a67e96ecab5; That
else branch just skipped my radar. Now I also (re-)looked all other
if/then/elif/else/fi parts to catch any other similar potential problems,
and did not notice anything.
