Patch taken from from upstream:
https://github.com/sam-github/libnet/commit/ffd7fab744a9ad2893169a8fb6244074604d5d0d

Adjusted the file paths manually so the patch applies to the packaged
libnet sources.

+Subject: [PATCH] Support musl libc, remove support for glibc < 2.1
+
+The workarounds for glibc < 2.1 (was released february 1999) break the
+build with musl libc.
+
+It is very unlikely that 2.0 or earlier is still in use, and if so,
+1) that's a big security hole
+2) code wouldnt compile anyway since noone tested build in the last decade
+3) user of it wouldn't expect anyway to get bleeding edge sw built on it,
+   so he would just use the latest version that works for him.
+
+Closes #52
