Allow command parameters for lsb_release to be combined

Is your feature request related to a problem? Please describe.

Earlier it was discovered that when trying to run brew on Photon OS, the way that it calls lsb_release is the common practice of combining parameters e.g. lsb_release -sd.

This, however, results in a syntax error within Photon since Photon's lsb_release does not support this behavior. Each parameter must be entered one at a time.

Describe the solution you'd like

Allow lsb_release to be called with combining short name parameters.

lsb_release -sd should behave the same as lsb_release -s -d

Describe alternatives you've considered

I have had to modify lsb_release by hand using a solution that works just enough to be able to get brew running within Photon, but this is not a good solution because my deployment script now has to deploy a custom system file in addition to my application code.

Additional context

I would imagine there are other linux tools that also use lsb_release in the same manner.

Start by locating the lsb_release entry point and the code that parses its command-line parameters. Check how combined short options such as -sd are handled, then verify that they behave the same as separate -s -d parameters; the issue does not name a test file.
