[PATCH] Fix PR48246

[Richard Guenther]

The LTO partitioning code asserts that at most the first partition
is empty (which should probably be also the last one).  It works
fine when other partitions are empty so there is no reason to barf
on users when they run into such partitioning cases.

Thus, committed as obvious.

Richard.
