well, the reason i'm mentioning this is because Android's mixing in
the bionic (lightly modified openbsd) fts to its host musl to be able
to build various things.
one of them is the bionic fts test (we build the bionic tests against
the host libc too, for comparison), so we can ignore that.
bionic/tests/fts_test.cpp:32:10: fatal error: 'fts.h' file not found
the other two seem legit though:
external/vboot_reference/futility/updater_archive.c:13:10: fatal
error: 'fts.h' file not found
external/selinux/libselinux/utils/selabel_get_digests_all_partial_matches.c:7:10:
fatal error: 'fts.h' file not found

iirc there's a way to grep the source of all debian packages, though
it would be hard to know how many of them have an alternative like
ftw(3) they can use instead.
