[Clfs-support] traceroute-2.0.12 - Bad value for ai_flags - Cannot handle cmdline arg

[Jason Aeschilman]

I have a Pure64 CLFS build completed and I'm adding packages from CBLFS.  I
came across the following issue with traceroute and a solution for it, which
I thought I would share with the list in case it proves helpful to someone.

I configured all packages in CLFS with "--disable-nls" to disable locale
support.  This way I can save some space by removing locale-related data
(see small-lfs.txt hint).  However, this appears to result in traceroute
failing to resolve names because it uses the AI_IDN flag with getaddrinfo()
and that apparently is not valid without locale support.  I would get the
following error whenever I tried to use traceroute:

# traceroute 10.0.0.1
10.0.0.1: Bad value for ai_flags
Cannot handle "host" cmdline arg `10.0.0.1' on position 1 (argc 1)

# traceroute www.yahoo.com
www.yahoo.com: Bad value for ai_flags
Cannot handle "host" cmdline arg `www.yahoo.com' on position 1 (argc 1)

The solution was simply to comment out the line that sets ai_flags to
AI_IDN.  Here is the patch:
