[Buildroot] [git commit] utils/brmake: print the error code of the build

[Thomas Petazzoni]

commit: https://git.buildroot.net/buildroot/commit/?id=c8d8f74a939ac1381d7ac7dee356247f91347ace
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Since the stdout and stderr streams are redirected, it is not
immediately obvious when a build failed, even though brmake really exits
with the same error code as make did.

When there is an error, print the exit code after the elapsed time.
