AIX fixes for branch-1.4

[Albert Chin]

1. When LDFLAGS="-Wl,-brtl,[other options]", the -brtl special-case
   code for AIX never gets triggered because were are being too
   specific about how we search for -brtl. Use case statement to
   avoid this.
2. Remove extraneous semicolon.
3. Recognize the IBM xlc compiler.

        * libtool.m4: When LDFLAGS="-Wl,-brtl,[other options]", the
          -brtl special-case code for AIX never gets triggered because
          were are being too specific about how we search for -brtl.
          Use case statement to avoid this. Remove extraneous
          semicolon.
        * ltmain.in: Recognize the IBM xlc compiler.
