contrib/buildsystems: handle options starting with a slash

dscho · gitster · commit 4553f9de23f8 · 2019-07-29T14:51:43.000-07:00
With the recent changes to allow building with MSVC=1, we now pass the
/OPT:REF option to the compiler. This confuses the parser that wants to
turn the output of a dry run into project definitions for QMake and Visual
Studio:

	Unhandled link option @ line 213: /OPT:REF at [...]

Let's just extend the code that passes through options that start with a
dash, so that it passes through options that start with a slash, too.
