ruby: fix 'pcrel too far' build problem on SuperH architectures 

The 'pcrel too far' problem detected in the autobuild on SuperH
architectures, seems to be caused by the -Os optimization flag. Using
standard optimization fixes the problem.

Fixes http://autobuild.buildroot.net/results/bc36e051e06f596c2fafdd3cc3745bb34b73ace3/
