Bug#741548: mruby FTBFS: build failed on post-compile-test on mips/mipsel

[Dejan Latinovic]

Hello,

I have backported changes related to this issue from 
the newest  version from github,
and created a patch that solves it for
mips/mipsel.

Could you please consider including 
these changes in a current version of mruby (1.0.0-1).

Thanks,
Dejan
