texinfo 6.1, 6.3: warning messages in no-locale setups

[Michael Deutschmann]

On my system, a vanilla build of texinfo 6.3 frequently outputs a message:

sh: 1: locale: not found
Couldn't set UTF-8 character type in locale.

In turn, this causes a dozen "make check" tests to FAIL.

The problem is one chunk of code that badly wants to find and change to a
locale with the wanted character set.  This is futile on my system as I
am running uClibc with locales compiled out.  There is no locale utility
and setlocale() is a constant function.

Oddly nothing seems to actually need to modify the locale.  If I
simply insert a "return 0;" in "xspara.c" to prevent the message, all
"make check" tests succeed.

This actually started with texinfo-6.1.
