on kernel-2.2.12-20's SPEC there is a bug on %build where
BuildPCMCIA would be called twice when there is an i386
Build, resulting on an error on a build of the spec as a
normal user, because of an attempt to overwrite a read only
file.

actually, the first files build for BuildPCMCIA are tagged
as BOOT and then overwriten for the final ones (if building
the spec as root).

as can be seen on the following extract of the kernel spec,
when arch = i386, the BuildPCMCIA instruction is called
twice,

...
#BOOT kernel
BuildKernel BOOT
%ifarch i386
BuildPCMCIA BOOT
%endif
SaveHeaders BOOT
...

#NORMAL KERNEL
BuildKernel
%ifarch i386 i586 i686
BuildiBCS no
BuildPCMCIA
%endif
....

actually the first call of BuildPCMCIA has no sense.., since
there isn't a corresponding -pcmcia package for boot
subpackage, so this could be commented, keeping like this

#BOOT kernel
BuildKernel BOOT
SaveHeaders BOOT
...
