Makefile: enable .DELETE_ON_ERROR special target

Browse Source 
msgfmt creates the output file even if there was a fatal error. Thus
make would stop because of the error return, but the output file would
be left on disk and running make again would continue building other
files. Enable the .DELETE_ON_ERROR special target to automatically
delete target files changed by failing commands. This affects all
rules; I think it is the correct behavior for all existing rules.
