Mike Frysinger 4fdd5ec125 ia64: fix set-but-unused warnings with syscalls 
These macros often set up a variable that later macros sometimes do
not use.  Add unused attribute to avoid that.

Similarly, the ia64 code tends to check the err field rather than
the val (which is opposite of most arches) leading to the same
kind of warning.  Replace this with a dummy reference.

Mike Frysinger a186dc916c ia64: fix strict aliasing warnings with libm error 
The current code declares double constants by using a char buffer and
then casting the pointer to a different type.  This makes the aliasing
logic unhappy.  Change it to use a union instead to avoid that.

Mike Frysinger c5abd7ce01 ia64: fix strict aliasing warnings with func descriptors 
Function pointers on ia64 are like parisc -- they're plabels.  While
the parisc port enjoys a gcc builtin for extracting the address here,
ia64 has no such luck.

Casting & dereferencing in one go triggers a strict aliasing warning.
Use a union to fix that.
