tcsh: compile with -fno-optimize-strlen

The gcc compiler optimization to replace a call of malloc followed by a
call of memset with a calloc call conflicts with tcshs own
implementation of calloc, which calls malloc and memset.

This bug is reported to and acknowledged by the maintainer (
http://mx.gw.com/pipermail/tcsh-bugs/2015-May/000930.html ) and should
be fixed in the next tcsh release.
