Build instructions now direct the user to have the CFE generate executables
with those names via the --program-prefix=llvm configure option.

llvm-svn: 19084

Add instructions for using the --program-prefix=llvm so that the CFE build
produces llvmgcc instead of gcc.

Remove unix specific code (use of errno and read) from the reader.
Thanks to Jeff Cohen for pointing this out.
