From: Thomas Petazzoni Date: Fri, 17 Jul 2009 06:53:55 +0000 (+0200) Subject: external toolchain: check cross-compiler existence X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=901b468e24ff546760ffdf6456d731f6388bad00;p=buildroot.git 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.
