config.mk: fix POSIX_C_SOURCE macro for feature test for snprintf() | |
The feature test was incorrect: | |
_POSIX_C_SOURCE=2 | |

http://man7.org/linux/man-pages/man7/feature_test_macros.7.html | |
A higher value is needed (atleast 1995): | |

FreeBSD feature test macro: | |
on | |
https://github.com/freebsd/freebsd/blob/master/include/stdio.h line 297 | |

This fixes a warning on FreeBSD, reported by Plasmoduck on IRC, thanks. | |
