This comes handy if you want to look at your application output without
having to save it into a file. For example, use this with aubinator from
Mesa :
$ intel_aubdump -c '/path/to/aubinator --gen=hsw' my_gl_app
v2: Fix handling empty command line option
v3: Fix command line concatenation (again...)
