No Issue - Disable VSX extensions (uplift)

There is no detection script for them as for AltiVec, and it's breaking older machines (PowerMac G5 in particular).

-       terrible ways, meaning the order of operations is critical here.
-
-       1. Replace \ with \\ first, because it is an escape character for
-       certain conditions in both parsers.
-
-       2. Escape double quotes with double backslashes.
-       
-       3. Escape ` and $ so commands do not get executed, e.g $(calc.exe) or

-       
-       4. Escape all characters we are not sure about with ^, to ensure it
-       gets to the MS Crt arguments parser safely.
-
-       5. The % character is special because the MS Crt arguments parser will
-       try and look for environment variables and fill them in, in-place. We
-       cannot escape them with % and cannot escape them with ^ (because it's
-       cmd.exe's escape, not the MS Crt arguments parser). So, we can get the
-       cmd.exe parser to escape the character after it, if it is followed by
-       a valid starting character of an environment variable.
-       This ensures we do not try and double-escape another ^ if it was placed
-       by the previous replace.
-
-       6. Lastly, we replace new lines with ^ and TWO new lines, because the
-       first new line is there to enact the escape command, and the second is
-       the character to escape (in this case new line).
