+Subject: [PATCH] Fix usage on musl libc
+
+A gcc compiled on musl does not define __gnu_linux__, it defines __linux__.
+Only on glibc does __gnu_linux__ get defined, but both define __linux__, so
+we should check for that instead.
+
+With this patch, libffi works perfectly, and passes its testsuite entirely
+on musl libc systems.
