compile perl on RPI2 failure in opbasic/arith.t

[Stefan Parvu]

Always make test fails here:

$ ./TEST opbasic/arith.t
t/opbasic/arith ... FAILED at test 175
Failed 1 test out of 1, 0.00% okay.
	opbasic/arith.t
### Since not all tests were successful, you may want to run some of
### them individually and examine any diagnostic messages they produce.
### See the INSTALL document's section on "make test".
### You may have to set your dynamic library search path,
### LD_LIBRARY_PATH, to point to the build directory:
###   setenv LD_LIBRARY_PATH `pwd`; cd t; ./perl harness
###   LD_LIBRARY_PATH=`pwd`; export LD_LIBRARY_PATH; cd t; ./perl harness
###   export LD_LIBRARY_PATH=`pwd`; cd t; ./perl harness
### for csh-style shells, like tcsh; or for traditional/modern
### Bourne-style shells, like bash, ksh, and zsh, respectively.

Something to do with floating point calculations on RBPi ?
