+Description: Use test -e instead of test -s to prevent build failing on BTRFS.
+ Btrfs reports a size of 0 for empty directories. Test -s not only checks
+ if a file exists but also if it it's size is nonzero. This causes the makefile
+ to try and create a directory that already exists and fail. The fix is to use
+ -e instead.
