Simplify the makefile slightly by always building acpi-ext.o when
CONFIG_ACPI is turned on.
Yes, this adds a little bloat to the other configs, but not much:
text data bss dec hex filename
839 41 0 880 370 arch/ia64/kernel/acpi-ext.o
Before:
text data bss dec hex filename
10952753 1299212 1334241 13586206 cf4f1e vmlinux
After:
text data bss dec hex filename
10953739 1299084 1334241 13587064 cf5278 vmlinux
(gdb) p 13587064 - 13586206
$2 = 858
Seems like a small price to pay for the benefit of not having to think
so hard about the multitude of ia64 configs when reading code/Makefiles.
