Hi Nelson,

(1) Please have a look at World/build.log.  When configuring ICU this should
report 'bigendian yes' same as found in World/libs/icu/icu-build/config.log.

Unfortunately the ICU maintainers (in their infinite wisdom) have decided to
ignore the result from configure and determine U_IS_BIG_ENDIAN from scratch
in common/unicode/platform.h line 371ff.

Perhaps there is a preprocessor symbol __MIPS__, __mips__, or similar (as
opposed to __MIPSEL__, __mipsel__, ...) that can be used to extend the code
in platform.h (the analogous extension for sparc in lines 388-390 was added
2012-06-19).  Otherwise you may have to define CPPFLAGS=-DU_IS_BIG_ENDIAN=1.

BTW: LuaJIT-2.0.3/src/lj_arch.h tests for
   defined(__mips__) || defined(__mips) || defined(__MIPS__) || defined(__MIPS)
and building luajittex should actually be possible.

Regards
Peter
