Fix issue with generalized compiler version output using the wrong flags

TYPE: bug fix

KEYWORDS: compile, version

SOURCE: internal

DESCRIPTION OF CHANGES:
Problem:
A generalized compile version check was proposed in #1987. This logic was implemented in #1942 but the originating logic contains a bug where the `-V` and `--version` flag commands' output is flipped.

Solution:
Use `-V` in the appropriate spot when `$status` is zero for the `-V` check, and respectively for the `--version` check.

LIST OF MODIFIED FILES: 
M       compile

TESTS CONDUCTED: 
1. With previous bad logic the compile log output shows a compiler error as the wrong flag is used to output version info. With the fix, the correct output now shows in the compile log.
