I had some trouble with random build failures in a large LTO project
and it turned out to be random seed collisions in a highly parallel build
(thanks to Honza for suggesting that)

There were multiple problems:
- The way to generate the random seed is not very random (milliseconds time plus pid)
and prone to collisions on highly parallel builds
- It's only 32bit
- Several users take the existing ascii seed and re-CRC32 it again, which
doesn't exactly improve it.

This patch changes that to:
- Always use 64bit seeds as numbers (no re-crcing)
- Change all users to use HOST_WIDE_INT
- When the user specifies a random seed it's still crc32ed, but only in
this case.

Passes bootstrap + testsuite on x86_64-linux.

The commands of the $(TOOLS_ZIP) rule include copying of two subtrees from the source tree (asm/ and classes/).

The commands of the $(TOOLS_ZIP) rule include copying of two subtrees from the
source tree (asm/ and classes/). If the source tree is read-only, the use of
cp's -p option here prevents the trees from getting deleted later in the rule
if they (or at least their directories) don't get marked writable.
