minor makefile issues

[Joe Eykholt <joe@nuovasystems.com>]

Hi All,

Due to my unusual environment, I ran into two issues when installing git 
1.5.2.4 from source.
Although these are unusual, they might not be unique and the fixes are easy:

    1.  The make install failed because of line 49 in templates/Makefile:
           (cd blt && $(TAR) cf - .) | \
           (cd '$(DESTDIR_SQ)$(template_dir_SQ)' && $(TAR) xf -)
    because I have CDPATH set, the 'cd blt' actually outputs the new 
directory on stdout
    which confuses the second tar.  Changing this to 'cd ./blt' fixes 
it.  Perhaps this could
    be considered a bash bug.

    2.  My home directory containing my build tree is NFS-mounted, and 
root doesn't have any
    permission to write it.  So, when doing 'make prefix=/usr/local 
install-doc' as root, I got these errors:

    # make prefix=/usr/local install-doc
    make -C Documentation install
    make[1]: Entering directory 
`/net/da01/home/jre/build/git-1.5.2.4/Documentation'
    rm -f doc.dep+ doc.dep
    rm: cannot remove `doc.dep': Permission denied
    make[1]: *** [doc.dep] Error 1
    make[1]: Leaving directory 
`/net/da01/home/jre/build/git-1.5.2.4/Documentation'
    make: *** [install-doc] Error 2

I'm not sure what the best fix is for the second problem.  rm -f ignores 
non-existent files but not permission errors.
I guess you could do 'rm -f doc.dep || true'.

No response necessary.  Just thought you might like to know about 
these.  Otherwise, git seems nice!

    Thanks,
