From a07e2f1e8ad049772cd24b7daa0a4a168f33bfba Mon Sep 17 00:00:00 2001

Subject: [PATCH] meson: modify gperf test to remove sh dependency
modifies the gperf test to instead rely on a file input
rather than piping in using sh, as sh is often not reliable
on Windows due to paths.
Also changes the if else ladder into a foreach loop.
