This is missing some indentation here, and also for other if statements
introduced below.
I'm wondering if build_path is the right name for this variable, since it looks
like
it returns another variant of the source directory?

As I don't have your meson MR applied here, instead of this change to NINJA I
have
installed ninja via pacman and use the following diff instead:
diff --git a/configure b/configure
index 67832e3bab..58d76ae15a 100755
--- a/configure
+++ b/configure
@@ -8232,7 +8232,7 @@ fi

--libdir "${pre_prefix}$libdir" \

I can confirm that this patch solves the linking issue and produces a working
qemu-system-ppc.exe which I was using as a quick test.
ATB,
Mark.
