configure fails on Fedora rawhide

[austin987]

I tried libressl-2.0.0.tar.gz on Fedora rawhide with glibc-headers-2.19.90-23.fc21.x86_64, but configure fails:
configure:3445: checking whether we are cross compiling
configure:3453: gcc -o conftest -Wall -Werror -std=c99 -g -Wno-pointer-sign -D_BSD_SOURCE -D_POSIX_SOURCE -D_GNU_SOURCE conftest.c >&5
In file included from /usr/include/stdio.h:27:0,
from conftest.c:11:

warning "_BSD_SOURCE and _SVID_SOURCE are deprecated, use _DEFAULT_SOURCE"

^

configure:3468: $? = 127
configure:3475: error: in /home/austin/libressl-2.0.0': configure:3477: error: cannot run C compiled programs. If you meant to cross compile, use--host'.
See `config.log' for more details

changing configure to use both _DEFAULT_SOURCE and _BSD_SOURCE works. See https://perkamon.alioth.debian.org/online/man7/feature_test_macros.7.php

I'll attach a patch.

Hi, we have since disabled -Werror by default, which should allow you to make progress past this issue. Please try the latest git source (run autogen.sh first)

Yep, 058914f builds fine with ./autogen.sh
&& ./configure && make. make check also passes 41 tests.

Great work!

Note that without the patch, gcc will print a ton of warnings:
grep -c "/usr/include/features.h:148:3:" make.txt
