Fix build failure in examples/standalone
Some versions of 'make' do not handle trailing white-spaces
properly. Trailing spaces in ELF causes a 'fake' source to
be added to the variable COBJS; leading to build failure
(listed below). The problem was found with GNU Make 3.80.
Using text-function 'strip' as a workaround for the problem.
