Ignore the top level build/ directory tree.

Ignore the top level build/ directory tree.

This tree is generated by gentoo tools and should be ignored by git.

Tested by observing that git does ignore the top level build/ tree,
but does report build/ subtrees within the kernel tree.

Some minor nits.

File .gitignore (right):

http://codereview.chromium.org/2512002/diff/1/2#newcode59
.gitignore:59: # gentoo build directory
I don't think this directory has anything to do with gentoo. Its left-over from
the debian build we use to have. I think kernelconfig may still be using it.

Done. (I thought the config building too was part of gentoo).

I wanted to make it explicit that this is a directory and this is a top level
directory.  Otherwise if someone introduces a directory or file 'build'
elsewhere in the kernel it would cause problems.
