Bad invocation of 'git rev-list' during alphad build

[gwillen]

When building alphad, in the middle of the build process I get the following output:

... (some output, and then:)

  CXX      compat/libbitcoin_util_a-glibc_sanity.o

... (and then some more output)

@gmaxwell is also seeing this, and thought it was due to his old version of Git. But I'm on git 2.3.6 on OS X, and he's on git 2.0.something on Linux, and we're both seeing the same thing. The offending call to git rev-list is inside share/genbuild.sh. I may take a closer look.

Fixed in Bitcoin recently, I believe.

Indeed, this is fixed in bitcoin/bitcoin@c1149f7 , and the solution is to hide the message (the error is harmless). I'll bring that over.
