[rabin@rab.in (Rabin Vincent)]

Fix the following error which occurs when building an ARM kernel with
GCC 4.5.0:

  arm-linux-gcc -Wp,-MD,kernel/.bounds.s.d  -nostdinc
  [command line edited to remove paths]
  -D__KERNEL__ -mlittle-endian
  -Wall -Wundef
  -Wstrict-prototypes -Wno-trigraphs -fno-strict-aliasing -fno-common
  -Werror-implicit-function-declaration -Wno-format-security
  -fno-delete-null-pointer-checks -Os -marm -fno-dwarf2-cfi-asm
  -mabi=aapcs-linux -mno-thumb-interwork -funwind-tables -D__LINUX_ARM_ARCH__=5
  -march=armv5te -mtune=arm9tdmi -msoft-float -Uarm -fomit-frame-pointer -g
  -DCC_HAVE_ASM_GOTO    -D"KBUILD_STR(s)=#s"
  -D"KBUILD_BASENAME=KBUILD_STR(bounds)"  -D"KBUILD_MODNAME=KBUILD_STR(bounds)"
  -fverbose-asm -S -o kernel/bounds.s kernel/bounds.c
  kernel/bounds.c:1:0: error: FPA is unsupported in the AAPCS
