Thanks for reporting this; I fixed this a slightly different and
simpler way.

    configure.in: fix external libblkid test for static link
    
    External libblkid needs -luuid when linking statically.
    
    Also fix up the bogus other-lib parameter in the libuuid test;
    $LIBUUID is the null string, so it doesn't do anything other than
    obfuscate the use of AC_CHECK_LIB.
