MIPS: delay.c: Check BITS_PER_LONG instead of __SIZEOF_LONG__
When building a 32-bit kernel for RBTX4927 with gcc version 4.1.2 20061115
(prerelease) (Ubuntu 4.1.1-21), I get:
arch/mips/lib/delay.c:24:5: warning: "__SIZEOF_LONG__" is not defined
As a consequence, __delay() always uses the 64-bit "dsubu" instruction.
Replace the check for "__SIZEOF_LONG__ == 4" by "BITS_PER_LONG == 32" to
fix this.
Introduced by commit 5210edcd527773c227465ad18e416a894966324f [MIPS: Make
__{,n,u}delay declarations match definitions and generic delay.h"]
