The minimal iconv() implementation in uClibc is dependent on locale
support being enabled, because it uses the codeset information in
the locale data.  The inconv.h file contains some preprocessor logic
to alert users to the problem early.  Although perhaps it would be
better to simply not supply iconv.h when locale support isn't enabled.

Locale support itself isn't likely to be the issue.  Even when full
locale support isn't enabled, uClibc always support the C|POSIX locales.
My guess would be that ogg player uses iconv() to convert message tags
to/from various codesets.

Well, you could check if iconv() use in ogg player configurable at build
time.  If not, you could hack around it or use an alternate iconv
implementation like libiconv (although it is pretty large).  Or you
could build your own locale-enabled uClibc dev env with buildroot.
