glib-2.0: Dont disable iconv for uclibc

Currently we stub out iconv in glib when building
for uclibc which is not needed and infact results
in building systems with false hope of having
iconv and they misbehave during runtime

-Upstream-Status: Inappropriate [embedded specific]
-
-We provide dummy implementation of iconv functionality if it does not find
-iconv which will be case with uclibc. We remove the check for iconv in configure
-
-This is needed when libintl and libiconv is not available. It wont have any
-impact on case when they are available.
