Linking problems when passing linker flags before files

[Jakub Nowak <j.nowak26@xxxxxxxxxxxxxxxxx>]

Hello,

when I compile my program like this `g++ -std=c++17 -lstdc++fs test.cpp -o
test` it fails to compile because of linker errors. The reasons is that
`test.cpp` should some before `-lstdc++fs`.
This is a serious problem because it's very hard to debug it.
I'm wondering, why is this required to have files before linker flags and
if I should report this as a bug.
