This is probably best done using the TARGET_USE_LOCAL_THUNK_ALIAS_P
macro that Danny Smith added to the main branch on 2004-04-08.  This
change could be back ported to 3.4.

Using a thunk alias avoids in some situations the linker adding a
stub between the thunk and thunk function.  Having a direct jump
from thunk to thunk function is necessary under HP-UX.  Thus, this
magic is important for systems other than GNU/Linux.
