Check attached build log.
Note: I killed the build because scons seems to have frozen at that point, no clue why.

Dear upstream...will you prepare a fix or should we wait for the successor that will have that fixed?
Seems doubtful anyone's gonna fix this, so either just filter/deactivate the flag, compile with a different compiler or deactivate/use-flag the "linux-urandom" module in einit's sconscript. the successor shouldn't have this particular issue.
