You'll want to build it down to a bin image, using the prog option:
scons board=EK-LM3S9B92 toolchain=codesourcery prog
Then take the resulting .bin image and flash that.

Adding programs to romfs will make the image grow, but I think it's
more likely that it may have just been that you tried to burn the full
elf file rather than the bin. There are ways to crunch those down as
well using the romfs=compress or romfs=compile
(
http://www.eluaproject.net/doc/v0.8/en_arch_romfs.html#mode). The
former will require Lua be installed, as I recall, and the latter
requires that you build a lua cross-compiler out of the eLua tree
using a compiler for your native platform
(
http://www.eluaproject.net/doc/v0.8/en_using.html#cross).
to "make clean" you can append a -c, like this:
scons board=EK-LM3S9B92 toolchain=codesourcery -c
It won't clean anything unless you specify the build dependencies
though, so you can just do "scons -c". You can use scons -h to get a
dump of the common command line options for building elua targets, and
scons -H for scons-specific options.
Best.
