[PATCH, obvious] Fix PR30079: abort on mingw

[Michael Matz]

the early-out in wild_sort is not enough, it might still be
that filenames are equal _and_ the wildcard list doesn't specify
a sort order either.  Don't call compare_section then.

Tested on all targets.

committed as obvious after convincing myself that I had a thinko here.
