# LIBICONV_PLUG is used in GNU's libiconv for redefinition of exports [e.g.
# from libiconv_open() to iconv_open()]. But in OpenWrt this variable is not set
# when building libiconv-full. So when MariaDB sets LIBICONV_PLUG it expects
# iconv_open() to be available for example, which is not the case - only
# libiconv_open() is. To address this prevent the variable from being set.
# libiconv-stub does not use this variable, so there is no harm in always doing
# this.
