[Buildroot] [PATCH 1/1] infra/Makefile.in: Fix format_arg issues after bump gettext-tiny to c6dcdcd

[Vadim Kochan <vadim4j@gmail.com>]

After bump gettext-tiny to c6dcdcd there was change which enabled
gettext's macroses by default in:

    https://github.com/sabotage-linux/gettext-tiny/commit/58187329ad9f00eb8c39379e7ee0b608dd14bab8

it leads libglib2 to fail with format_arg issues. So fix it by disabling
these macroses and use rather external functions which requires linking.

I dont feel like this is a good solution actually. I need to clearly understand
why just using gettext's macrosses does not work for libglib2. But anyway I am
sending this patch to show the possible solution.
