[PATCH 05/12] linux-user: Extract target errno to 'target_errno_defs.h'

From:	Philippe Mathieu-Daudé
Subject:	[PATCH 05/12] linux-user: Extract target errno to 'target_errno_defs.h'
Date:	Sun, 4 Jul 2021 20:37:48 +0200

We want to access the target errno indepently of the rest
of the linux-user code. Extract it to a new target-specific
header: 'target_errno_defs.h'.
