[Minios-devel] [UNIKRAFT PATCH v2 1/6] build: buildrule: Strip arguments

[Simon Kuenzer <simon.kuenzer@xxxxxxxxx>]

Strip leading and trailing whitespaces from all given arguments
at the buildrule demultiplexer `buildrule`. This removes unexpected
behavior because of white spaces when implementing a buildrule.
