bug#18003: texlive-2014 fails to build on MIPS

[Mark H Weaver]

texlive-2014 contains a copy of luajit which fails its test suite on
MIPS, thus causing the entire build to fail on guix.  Here's the tail of
the build log:

Here's the contents of luajiterr.log on Loongson 2F:

--8<---------------cut here---------------start------------->8---
../../../texlive-20140525-source/libs/luajit/luajiterr.test: line 6:  9268 
Illegal instruction     ./luajittry -e "error('test')" 2> jiterr.tmp

< ./luajittry: (command line):1: test
< stack traceback:
<       [C]: in function 'error'
<       (command line):1: in main chunk
--8<---------------cut here---------------end--------------->8---

On Loongson 3A, it's almost the same except that it's "Bus Error"
instead of "Illegal instruction".

I will investigate further and report back.
