Subject: [PATCH] scripts/dtc: Call pkg-config POSIXly correct

Running with POSIXLY_CORRECT=1 in the environment the scripts/dtc build
fails, because pkg-config doesn't output anything when the flags come
after the arguments.

Fixes: f8d8b46cd20e ("scripts/dtc: use pkg-config to include <yaml.h> in non-standard path")
Signed-off-by: Thomas Bracht Laumann Jespersen <t@...mann.xyz>

I'm aware that the full kernel doesn't build with POSIXLY_CORRECT set, but I
asked around and was told just to submit a patch.

This is based on the v5.17-rc2 tag, not sure if that's the right tree to work
from, I'll happily cherry-pick to another tree if desired.
