[PATCH] alpha: Select HAVE_ARCH_COMPILER_H

[Matt Turner]

Alpha already provides asm/compiler.h (wrapping uapi/asm/compiler.h)
which defines architecture-specific compiler intrinsics like
__kernel_cmpbge, __kernel_cttz, __kernel_ctlz, and __kernel_ctpop.

Selecting HAVE_ARCH_COMPILER_H causes linux/compiler_types.h to include
asm/compiler.h, making these definitions available consistently.
