Initial Package Version: See Below

Applies to both glibc-2.2.5 and glibc-2.3.2, and probably glibc cvs as of Aug 2004.
Needed to build glibc with linux kernels 2.4.23 or higher on ARM, 
Fixes following error:

../sysdeps/unix/sysv/linux/arm/ioperm.c: In function `init_iosys':
../sysdeps/unix/sysv/linux/arm/ioperm.c:103: error: `BUS_ISA' undeclared (first use in this function)
../sysdeps/unix/sysv/linux/arm/ioperm.c:103: error: (Each undeclared identifier is reported only once
../sysdeps/unix/sysv/linux/arm/ioperm.c:103: error: for each function it appears in.)
../sysdeps/unix/sysv/linux/arm/ioperm.c:103: error: initializer element is not constant
../sysdeps/unix/sysv/linux/arm/ioperm.c:103: error: (near initialization for `iobase_name[1]')
