Subject: Compiling current SVN fails with the following error for me:
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=be5be0ec5abb6cf88d24d9b17329a206938006ec;p=buildroot.git

Compiling current SVN fails with the following error for me:

 cc1: warnings being treated as errors
 buildroot/buildroot/build_powerpc/makedevs/makedevs.c: In function main:
 buildroot/buildroot/build_powerpc/makedevs/makedevs.c:531: error:
 ignoring return value of system, declared with attribute warn_unused_result

This change adds a simple warning if system() fails.
