Hi,
this by no means could be considered a patch, it is only a
report of the modifications i had to make to git-1.6.4.2
sources in order to build it with uClibc-0.9.30.1 in Rob Landley's
Firmware Linux 0.9.7 in a armv6l qemu emulator.
The major problem really was to get perl to build.
I've tested git (mainly git pull as it is the only thing I really
need in this case) and it seems to work fine.
Attached you'll find a diff and my config.log.
Maybe some more experienced developer with better knowledge
of Makefile/autoconf voodoo could use this to add uClibc support
to git if there is a interest.

Best regards and Ciao,
Tito
