Possible race condition building libraries: head/amd64 r303329 -> r303379

[David Wolfskill]

I track head daily on both my laptop and a "build machine;" I only saw a
problem on the latter -- not on my laptop.

(The build machine is a bit beefier, and uses an SSD as its non-volatile
storage; the laptop uses a hybrid disk -- in case that is useful.)

As indicated in the Subject, in each case I was performing a
source-based upgrade-in-place from r303329 to r303379.  (And I've
been doing this routinely for quite some time.)

The build failed (initially -- a restart worked):

I have the complete typescript, and can (e.g.) place it on my Web
server if that would be useful.

freebeast(12.0-C)[6] cat /etc/src.conf

The build process was performed by an alias that expands to:
setenv TMPDIR /tmp && \
 id && \
 mount && \
 cd /usr/src && \
 uname -a && \
 date && \
 make -j16 buildworld && \
 date && \
 make -j16 buildkernel && \
 date && \
 rm -fr /boot/modules.old && \
 cp -pr /boot/modules{,.old} && \
 make installkernel && \
 date && \
 pushd /usr/ports && \
 pushd x11/nvidia-driver && \
 make clean ; popd ; popd && \
 date && \
 mergemaster -U -u 0022 -p && \
 date && \
 rm -fr /usr/include.old && \
 date && \
 mv /usr/include{,.old} && \
 date && \
 rm -fr /usr/share/man && \
 date && \
 make installworld && \
 date && \
 mergemaster -F -U -u 0022 -i && \
 date && \
 make delete-old && \
 date && \
 df -k

(It turns out that both the build machine and the laptop use -j16.)

Peace,
