Build error with C locale 4.14rc2

[OHKAWA Yuichi]

Hi,

When I tried to build 4.14rc2 with LC_ALL=C locale, a build error have occurred.
If I used LC_ALL=en_us.utf8, I had no error.

I guessed that because python3.6 under C locale cannot treat  a latin character ö of source4/heimdal/lib/asn1/lex.l.
