commit hash in config.mk causing git error while building ISO

[Roman Sokolkov]

Environment:
- Ubuntu 13.04
- git 1.8.1.2 (default one for 13.04)

Description:
I'm trying to rebuild Fuel 5.0 iso. And specified commit hash in config.mk
FUELLIB_COMMIT?=89ccab7ee76980e38c4d9a5fbcdf7df87e35d61f

"make iso" fails with git error:

warning: Could not find remote branch 14fa5cd3f6b56f835dc20272eb6402d560eb887d to clone.
fatal: Remote branch 14fa5cd3f6b56f835dc20272eb6402d560eb887d not found in upstream origin

How to reproduce:
# git --version
git version 1.8.1.2 <--(or newer)
#git clone --depth 1 --branch 14fa5cd3f6b56f835dc20272eb6402d560eb887d https://github.com/stackforge/fuel-library.git fuel-lib

root@ubuntu:~/fuel-main# Unexpected end of command stream

Details:
It works fine on Ubuntu 12.04 that has git version 1.7.9.5
Somewhere between 1.7.9.5-1.8.1.2 were changes that cause this behaviour. (it works just for branches and tags now)

This line should be refactored in favor new changes.

It does not work by design, unfortunately. There is no ability in git to fetch remote sha commit. You can work with tags and branches.
