target/makedev: fix compile breakage from unused result warning

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.
