kbuild: genksyms fix for typeof handling
The tokenizer misses counting an open-parenthesis when parsing a
non-trivial typeof beginning with an open-parenthesis. This function
in include/linux/ceph/libceph.h
static type *lookup_##name(struct rb_root *root,
typeof(((type *)0)->keyfld) key)
When instantiated in net/ceph/mon_client.c, causes subsequent symbols
including an EXPORT_SYMBOL in that file to be lost.
