According to the function `comp-trampoline-compile', the 
EMACS_INHIBIT_AUTOMATIC_NATIVE_COMPILATION environment variable 
does not prevent trampoline compilation, only the saving of the 
output of said trampoline compilation to the file system.

I just checked, EMACS_INHIBIT_AUTOMATIC_NATIVE_COMPILATION is 
already set to t anyway. Sean exported it from dh_elpa_test just 
before Christmas (65a588ca).

As of now, from what I understood of what I read in the upstream 
mailing list and the comp.el file, the only way to truly prevent 
trampoline compilation of a primitive is to add it to the variable 
`native-comp-never-optimize-functions'. I think it could also be 
possible to prevent the trampoline compilation of *any* primitive 
by setting `comp-enable-subr-trampolines' to nil.

Best,

Aymeric
