I've confirmed that both of the following allow make to give sane output
for me.  And they are better than my suggestion in the respect that the
error messages are according to the otherwise prevailing locale, not
suddenly switched to English.

# Avoid funny character set dependencies
unexport LC_ALL
LC_COLLATE=C
export LC_NUMERIC

# Avoid funny character set dependencies
unexport LC_ALL
LC_COLLATE=C
LC_NUMERIC=C
export LC_COLLATE LC_NUMERIC

I did not verify that they do something sensible for the awk concern
that originally introduced the locale change - but I think it is
unaffected by my locale settings.
