* BuildPlatformMain supports overriding HOST_LIBROOT on the target now,

so one can set it to the static libroot, if desired.
* Generic attribute emulation:
  - Added build tool rm_attrs, a simple "rm" replacement, which also
    removes the attributes directory for a given file.
  - Added build/scripts/rm_attrs shell script, which wraps the
    invocation of the rm_attrs tool. If it doesn't exist yet, the
    ordinary rm is used.
  - The RM jam variable refers to the rm_attrs script now, i.e. whenever
    something is removed by the build system, the attributes are removed
    too (if the build tool has already been built, that is).
  - Removed the shell function attrrmrf() in build_haiku_image. We use
    the rm_attrs tool instead, if necessary.
