[5.1.4] Error when compiling for Blackfin + uClinux

[Gilles Ganault <gilles.ganault@...>]

Hello

The most recent release of the uClinux-dist (2009R1.1-RC4) contains
"lua", so I enabled this option through "make menuconfig", followed by
"make single" (to avoid mixing output from two cores), but it fails
compiling Lua 5.1.4:

make[7]: *** [lua] Error 1
=======================

Has someone successfully compiled Lua 5.1.4 on uClinux-dist for the
Blackfin CPU? Any idea what could be causing this error?

I assume no one has really used Lua on that platform and figured I had
more chance of asking here instead.

Thank you.
