Hello,

This patch does two things:

- It modifies "infcall.c" so that it converts the entry-point address 
into a code address (it might be a descriptor).

- since it's now redundant, for ppc64 GNU/Linux, it stops setting 
entry_point_address

Kevin, ppc64 part ok?  It doesn't immediatly affect test results as this 
GDB still requires a mod to relocate the entry point.
