[PATCH 5.16 0473/1017] scripts/dtc: Call pkg-config POSIXly correct

From: Greg Kroah-Hartman
Date: Tue Apr 05 2022 - 08:39:29 EST

From: Thomas Bracht Laumann Jespersen <t@xxxxxxxxxxx>

[ Upstream commit a8b309ce9760943486e0585285e0125588a31650 ]

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: 067c650c456e ("dtc: Use pkg-config to locate libyaml")
