Why are you building the Git branch instead of building the release
tarball?  Building from Git takes much more time, for starters, and
technically you don't build the same sources as the ones released.

My guess would be that building and installing in one go, and with
such a high parallelism at that, causes some conflicts, whereby two
programs access the same file together, and one of them attempts to
rename/remove the file.

My suggestion is first build with "make -j20 ..." and then install
with "make install-strip".  The latter doesn't need such high
parallelism anyway, since it basically processes stuff serially.
