[racket] disable inlining

How do I disable inlining?

I have tried "--no-jit", "PLTNOMZJIT", and "eval-jit-enabled".

stamourv pointed out "raco make --disable-inline", but this app is built 
using "raco setup", and this app is peculiar anyway, so I before I 
started reworking the build process, I thought I'd double check.

Reason for asking...

  I have a large system that works with 5.2.1, but breaks strangely with 
5.3 and later.  It does evals and dynamic requires, and so, under 5.3 
and later, there are runtime messages like:

mzc optimizer: inlining: involving: #(xxx #<path:/yyy/zzz.ss> 1302 2 
57481 33 #f) size: 1 threshold: 64

Part of the list result of this inlined procedure seems to be involved 
in the misbehaving code.

I'd like to rule out that the problem is caused by inlining.
