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

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
-isystem /usr/local/x86_64-portbld-freebsd10.0/include
-isystem /usr/local/x86_64-portbld-freebsd10.0/sys-include
-fomit-frame-pointer -Usun -fclasspath=
--encoding=UTF-8 -Wno-deprecated -fbootstrap-classes -g -O2 -c
-MT javax/management.lo -MD -MP -MF javax/management.deps
@javax/management.list  -fPIC -o javax/.libs/management.o jc1: fatal
error: error writing to /tmp/ccmi9d4D.s: No space left on device

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