glibc-locale-dependency.patch

As I tried to build glibc today, I hit a snag during the locale generation. 
First it complained that /usr/share/i18n/charmaps did not exist, so I installed
the locales package on my system, but then 'bitbake glibc' still complained
about syntax errors in the locale definition files.  I tried various ways to
fix it until I realized that my Debian system is running glibc 2.4 while the
distribution I'm working on requires glibc 2.3.  The locale scripts are
apparently not compatible across glibc versions.  I concluded that OpenEmbedded
*must* *not* depend on /usr/share/i18n when building glibc.

I poked around until I found packages/glibc/glibc-package.bbclass, which
contained the following line:

    i18npath = os.path.join(treedir, datadir, "i18n")

The Python os.path.join has a little surprise.  If a parameter after the first
parameter specifies an absolute path, the new path replaces rather than
augments the earlier path.  For example, os.path.join('/home/user', '/tmp')
yields the string '/tmp' rather than '/home/user/tmp'.  I wish this behavior
were more obvious, but alas, that is a deeper issue.

I will attach a patch that fixes this issue for me.  Although the patch is made
for the org.openembedded.oz354x branch, I believe all branches need this patch.
 The patch may also solve other bugs related to glibc building, but I don't
know which.
