Thank you. I checked out v0.80, compiled luatex with --nostrip option,
copied the luatex binary to my TeXLive distribution, rebuilt the
formats (with fmtutil --byengine luatex), and everything worked after
that.

I definitely had to rebuild the formats to get it working. (otherwise
it gave me the dreaded “I’m stymied error”)

I copied over the binary to another file called luatex-stripped and
ran strip -u -r  on that. Both copies seem to load the shared library
just fine. Here are the results:

$> cp luatex luatex-stripped

$> nm luatex | wc -l
24277

$> strip -u -r luatex-stripped

$> nm luatex-stripped | wc -l
363

$> ~/code/personal/luatex/v-0.80/bin/luatex --luaonly test.lua
Deepak

$> ~/code/personal/luatex/v-0.80/bin/luatex-stripped --luaonly test.lua
Deepak

So I guess it is an option to use strip -u -r luatex
