From 901b468e24ff546760ffdf6456d731f6388bad00 Mon Sep 17 00:00:00 2001 From: Thomas Petazzoni Date: Fri, 17 Jul 2009 08:53:55 +0200 Subject: external toolchain: check cross-compiler existence As a minimal test to the external toolchain, check that $(TARGET_CC) is actually an existing executable file. That way, if the user misconfigures the toolchain path and/or prefix, a meaningful error message will be shown.
