[OE-core] [PATCH] gettext: fix implicit build result

[rongqing.li at windriver.com]

From: Ming Liu <ming.liu at windriver.com>

Some "once only" variants are being defined instead of standard autoconf
macros, for instance, AC_CHECK_HEADERS_ONCE like AC_CHECK_HEADERS. The
advantage is that the check for each of the headers will be put only once
into the 'configure' file, therefore it keeps the size down. But there is
also a drawback that the checks then will turn to be statically inserted
to the configure and cannot be conditionalized any more. It will
definitely break the dependencies chosen as internally included.

Turns AC_CHECK_HEADERS_ONCE back to AC_CHECK_HEADERS for those cases.
