Klemens, Benoit,
rovert@ had noticed that git out of the box uses as many threads as the
system has CUPs. claudio@ had pointed that it is quite bad idea and use an
example that ld.lld with -Wl,--threads=1 reduces the configure time by 15%
and system time by 40%.
So, here the diff which replaces 0 threads to 1 by default where it isn't 1
already, and disabled try to use threads in name-hashing.
Are you ok with it?
