The failures for the ovsdb-server tests are because of the POSIX
noncompliant version of "diff" that Alpine includes by default.  Install
a POSIX-compliant diff (e.g. "apk add diffutils") to fix the problem.

The failure of test 761 seems to be a memory error.  Running under
valgrind, with "make check-valgrind TESTSUITEFLAGS=761", I get a useless
backtrace though:

    ==29841== Invalid free() / delete / delete[] / realloc()
    ==29841==    at 0x4C92A6E: free (vg_replace_malloc.c:530)
    ==29841==    by 0x405717F: ??? (in /lib/ld-musl-x86_64.so.1)
    ==29841==  Address 0x4e9a180 is in a rw- mapped file /usr/lib/valgrind/vgpreload_memcheck-amd64-linux.so segment

What does it take to get useful valgrind results on Alpine?

Thanks,

Ben.
