It is not related to inodes, confirmed by appending output of df -ih to
a file by means of cron job that runs every minute:

tmpfs         128M    388K    128M     0%      39  459k    0%   /tmp

tmpfs         128M     18M    110M    14%      50  459k    0%   /tmp
tmpfs         128M     39M     89M    30%      72  459k    0%   /tmp

Somewhere in 10th minute it fills up /tmp which breaks building,
and whatever build process created in /tmp is removed.

This is the point of failure:
libtool: compile:  /usr/ports/lang/gcc/work/build/./gcc/gcj

error: error writing to /tmp/ccmi9d4D.s: No space left on device

I'll try to increase /tmp to 512Mb and see what happens.
