[patch] fix IPMI build error #if CONFIG_ACPI_HT_ONLY

[Adrian Bunk]

I got the following build error in 2.6.0-test2:

<--  snip  -->

...
  LD      .tmp_vmlinux1
...
drivers/built-in.o(.init.text+0xdff5): In function `init_ipmi_kcs':
: undefined reference to `acpi_find_bmc'
make: *** [.tmp_vmlinux1] Error 1
$ grep ACPI .config
# Power management options (ACPI, APM)
# ACPI Support
CONFIG_ACPI=y
CONFIG_ACPI_HT_ONLY=y
$ 

<--  snip  -->

acpi_find_bmc is only available #ifdef CONFIG_ACPI_INTERPRETER.

The following patch fixes it (the same problem does exist in
2.4.22-pre8, the patch applies with a few lines offset):

        of the darkness. There had been need of rain for many days.
       "Only a promise," Lao Er said.
