Subject: [PATCH 3/5] Makefile: Generate error_strings.h

This is an initial attempt and needs improvement.  Ideally,
error_strings.h should only be generated when STRERROR or STRERROR_NAME
are enabled. This implementation also fails to remake error_strings.h
when arch-specific dependencies change.  Also, I've noticed that this
implementation fails to output a message when it's running, so help with
this would be appreciated.
