[Buildroot] [PATCH v3 1/1] package/gettext: Fix GETTEXTIZE is not defined in case of full gettext

[Vadim Kochan <vadim4j@gmail.com>]

After introducing gettext-tiny in:

	5367a1b253 package/gettext-tiny: new package

GETTEXTIZE variable is conditionally defined separately by gettext-gnu
or gettext-tiny package depending on which of them is enabled. But it
causes the issue when BR2_TOOLCHAIN_HAS_FULL_GETTEXT=y, because in that
case BR2_PACKAGE_GETTEXT is not selected by BR2_SYSTEM_ENABLE_NLS config
and GETTEXTIZE is not defined, which causes build fail for packages
which uses gettextizing (e.g. host-flex).

Fix issue by defining GETTEXTIZE unconditionally in
package/gettext/gettext.mk. It is not needed to define it in each
gettext-*.mk because the difference is only in passing 'data_dir'
parameter which points to ${PREFIX}/share/gettext-tiny (in case of
gettext-tiny provider), but simple linking:

	${PREFIX}/share/gettext -> ${PREFIX}/share/gettext-tiny

solves this issue.

v3:
    Make commit message more descriptive and cleaner, also fix 'data_dir'
    explanation which was not updated in v2.

v2:
    Do not use ${PREFIX}/share/gettext-tiny as 'data_dir' param for
    gettextize, but instead create link ${PREFIX}/share/gettext -> ${PREFIX}/share/gettext-tiny.
    It allows to have common invovation of gettextize in package/gettext.mk
