At <http://gcc.gnu.org/wiki/Top-Level_Libgcc_Migration> I listed this 
macro, and lots of others, under "used by the compiler itself and libgcc 
(probably predefine macros if -fbuilding-libgcc in most cases, unless 
predefined macros considered more generally useful)".  I think that 
approach still makes sense for improving the host / target tm.h 
separation: use these tm.h macros directly only in the compiler, and make 
the compiler, if -fbuilding-libgcc, predefine a macro for use in GCC's own 
libraries.

So far only TRAMPOLINE_SIZE is handled like that; conversions of other 
macros are welcome.  The list on that wiki page may be a bit out of date, 
but should still be a good starting point for this project.
