Fix broken </tt> tag on the clustering docs

There is a missing '<' in the clustering documentation for the
--id option [1] which makes the output look like this:

    –id can be used with –sparse/tt>.

This patch adds the missing symbol making it properly display
as:

    –id can be used with –sparse.

NOTE: This is a single character change better viewed with the
`--word-diff` option.

Fix compilation of Boost with gcc 4.8.2.

This applies an upstream patch [1] that fixes a compilation of Boost on
newer versions of glibc which unconditionally assume int64_t support.

See [2] for more.

Add patch to libhdfs to fix building on x86_64 with gcc 4.8.2.

There is a `fprintf()` call in hdfs.c in hadoop 1.0.1 that incorrecly
prints a `size_t` type with the format specifier of "%d". The correct
specifier is "%zu" [1]. At least gcc 4.8.2 complains about this and
aborts the build.

This commit adds an additional patch to hadoop 1.0.1 to correct this.

[1] See `man 3 printf`
