The building of drivers/acpi/acpica/utglobal.o is throwing
a number of sparse warnins about undeclared symbols. This is
due to defining DEFINE_ACPI_GLOBALS then making the macro
ACPI_INIT_GLOBAL() define it but never declaring the fact this
is an extern declared varible.

This is some of the sparse warnings that are being fixed here:

drivers/acpi/acpica/utglobal.c: note: in included file (through include/acpi/acpi.h):
./include/acpi/acpixf.h:104:1: warning: symbol 'acpi_gbl_enable_interpreter_slack' was not declared. Should it be static?

Note, if this isn't the correct place to fix, where should this be
going?
