options: Add --v option

options: Add --v option

It's been requested a long ago to handle '--v' option same was as
a regualar '-v'. From initial report

 | NASM and yasm are in many respects compatible but yasm uses --v
 | instead of -v for version.  As often --v is used for version I
 | end up using --v initially in NASM.  This patch allows me to compile
 | Mozilla apps which use yasm with NASM by merely renaming NASM to yasm
 | so that the build environment does not have to be updated (Mozilla
 | would not accept changes to allow use of NASM).
