From 527413ec243564a89ffaad6368d446de44415970 Mon Sep 17 00:00:00 2001
From: Chen Qi <Qi.Chen@windriver.com>

Subject: [PATCH] Fix to run efi_cc and efi_ld correctly when cross-compiling

When cross-compiling, efi_cc and efi_ld may take the form of
'xxx-gcc --sysroot=xxx', and this would cause run_command and
the alike fail.

Fix to split them to make commands run correctly.

Upstream-Status: Pending
