Downloads some prerequisites needed by GCC. Run this from the top level of the
GCC source tree and the GCC build will do the right thing.
The following options are available:
--directory=DIR download and unpack packages into DIR instead of '.'
--force download again overwriting existing packages
--no-force do not download existing packages again (default)
--isl download ISL, needed for Graphite loop optimizations (default)
--graphite same as --isl
--no-isl don't download ISL
--no-graphite same as --no-isl
--verify verify package integrity after download (default)
--no-verify don't verify package integrity
--sha512 use SHA512 checksum to verify package integrity (default)
--md5 use MD5 checksum to verify package integrity
--help show this text and exit
--version show version information and exit
