[Minios-devel] [UNIKRAFT PATCH] build/rules: Provide `src2dst` function

[Simon Kuenzer <simon.kuenzer@xxxxxxxxx>]

`src2dst` converts a list of sources to paths pointing to their
corresponding destination files to a given filename suffix/extension.
This is a more generic case than `src2obj`. `src2obj` is changed to
call `src2dst` with the '.o' suffix.
