musl - strerror_r and _GNU

Subject: strerror_r and _GNU_SOURCE

When _GNU_SOURCE is defined, strerror_r should return a char *. Musl
1.1.19 declares strerror_r as:

	int strerror_r (int, char *, size_t)

I have found that _GNU_SOURCE is defined when I build snort on OpenWrt
(OpenWrt uses musl). This causes the build to fail because snort expects
strerror_r to return a char * since _GNU_SOURCE is defined.

Is this a bug in musl?
