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

[Yann E. MORIN <yann.morin.1998@free.fr>]

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.
