Paolo 'Blaisorblade' Giarrusso 9c340d80f6 [PATCH] uml: fix compilation for __CHOOSE_MODE addition
I had added the __CHOOSE_MODE syntax to fix some warnings with newer GCC's
in the uml-fix-cond-expr-as-lvalues-warning patch.

Here is the update from the version I sent to make it work also when only
one mode (TT or SKAS) is enabled.
