Build samples in parallel with "make -jN"

Browse Source 
Building samples one by one has become a significant pessimization
nowadays, when multicore machines are much more common than single core
ones, so get rid of the shell loop which built the samples one by one
and use make targets to let make build as many targets at once as
desired.

Closes https://github.com/wxWidgets/wxWidgets/pull/536
