From: Baruch Siach Date: Thu, 3 Jul 2014 16:32:58 +0000 (+0300) Subject: toolchain/helpers.mk: don't discard check_arm_abi stderr X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=8420d4c169c78bc54d6bc6ef7a7e7c2be50052df;p=buildroot.git toolchain/helpers.mk: don't discard check_arm_abi stderr Since we only need to know whether the compiler runs successfully, and stderr is empty for the success case, there is no need to redirect stderr to /dev/null. Moreover, stderr output of the failing case reveals valuable information on the real failure reason.
