I can see it, toolsDependencies[2] version 2.5.0-4-69bd9e6
url: https://github.com/earlephilhower/esp-quick-toolchain/releases/download/2.5.0-4/i686-w64-mingw32-mklittlefs-69bd9e6.zip

Not correct, the file you refer to is for use with a 32bit mingw environment running within 64bit Windows, not for native 32bit linux. For this the file would be "i686-linux-gnu.mklittlefs-7f77f2b.1563313032.tar.gz"

edit Sorry I misread the issue. You are in the need of Linux, not Windows.
(reading too quickly and because of that Operating System: [Windows|Ubuntu|MacOS] in OP, eyes catch what they want to)

@earlephilhower It seems linux/686 entry for mklittlefs has disappeared in this commit
