Standalone linuxbrew on SL5.5

# Mostly based on this:
#  https://github.com/Homebrew/linuxbrew/wiki/Standalone-Installation
# But I started with nothing (no ruby, no gcc)

# Ruby and GCC will go here
mkdir bootstrap

# Get GCC 4.4 and install under bootstrap
# We also need libstdc++ when we get to building gcc-4.9 because somebody decided it was a good idea to start writing GCC in C++
