[commit] Remove unused function in irix5-nat.c

Ulrich Weigand
Hello,

this removes another never-used function, get_longjmp_target in irix5-nat.c.

This hasn't been used in a while; to properly support longjmp on irix
gdbarch support needs to be added to mips-irix-tdep.c instead.

Committed to mainline.

Bye,
Ulrich

ChangeLog:

        * irix5-nat.c (JB_ELEMENT_SIZE, get_longjmp_target): Remove.
