progress with gub

[Joe Neeman]

I have an x86 chroot now and gub completes "make -f lilypond.make bootstrap". 
But if I try "make -f lilypond.make all", I get:

executing pipe git --git-dir /home/joe/lilypond/downloads/lilypond.git 
log --max-count=1 --pretty=oneline -git.sv.gnu.org-lilypond.git
fatal: bad default revision 'HEAD'

Running "git --git-dir /home/joe/lilypond/downloads/lilypond.git branch" gives 
me

and I can do, for example,
"git --git-dir /home/joe/lilypond/downloads/lilypond.git log 
master-git.sv.gnu.org-lilypond.git" without an error. Whenever I try to look 
at the log for the "-git.sv.gnu.org-lilypond.git" branch, though, it 
says "fatal: bad default revision 'HEAD'".
