[Clfs-dev] [PATCH] md5sum checksum improvement

[Cheng Renquan]

The md5sums of every packages and patches are already recorded in the BOOK,
but they have few opportunies to be checked,

Here is a new stylesheet md5sum.xsl, to parse md5sum values of every packages
and patches from the BOOK and output a md5sum recognizable file, so after we
downloaded all packages and patches, we can just check them.

This is a very preliminary idea, and need more work to integrate into the
BOOK Makefile, and here is the usage to produce a mips64.md5sum:

  $ xsltproc --xinclude --nonet --output mips64.md5sum \
      stylesheets/md5sum.xsl materials/mips64-chapter.xml

Using this, I found the error in the previous eglibc-ports-md5sum fix patch.
