reporting worked around kernel build failures for 5.0.2

["Noah McNallie" <n0ah%n0ah.org@localhost>]

Hey guys. Today I was in the need to compile a kernel for various reasons  
so I figured while I was at it I would slim the generic kernel down to the  
bare minimals that i could conclude i need for use with vmware player.

Amongst doing so, I ran into kernel build errors.

The first error I don't readily have available though if someone would  
like me to reproduce it i'm quite confident I can. It showed itself when  
ipfilter devices and options where enabled along with a pf device. I got  
lucky by guessing that one quickly (it seems almost every one of my netbsd  
kernel building issues have stemmed from options/devices being enabled  
while another one is or is not, and for some reason 'config' is not  
catching the majority of these issues). These where not actually errors  
they where warnings that died because warnings where being treated as  
errors. When I looked at the source it had something to do with empty if  
statements with no blocks.

With that resolved I started nice -n 20 ./build.sh  
kernel=sys/arch/i386/conf/NBSDVM release

This is what I got next (and though perhaps it's rather stupid of me in  
some circumstances to not or to have certain options enabled without  
others, it stems from not doing a completely thorough job on removing  
features when i'm not 100% sure if I should or not)

as for the tcic, i had to comment out the following:

#tcic0  at isa? port 0x240 iomem 0xd0000 iosiz 0x10000

as for the i82365, i saw it was trying to use a function for pcic, which i  
searched in the config, and commented out any lines i had left pertaining  
to pcic, which i believe was cardbus support via the pci bus.

then for the machdep.c, well it had assumingly externed this cpu_exec_aout  
stuff and was not linking to anything that defined it... so i looked in  
the config file once again and and commented out the following:

# For GENERIC, we build the exec formats as modules by default.
#no options        EXEC_AOUT       # exec a.out binaries
#no options        EXEC_ELF32      # exec ELF binaries
#no options        EXEC_SCRIPT     # exec #! scripts
#no options        COREDUMP

the kernel built, now as i'm building release, everything else has  
proceeded to being built, and that is where i'm currently at.

hopefuly this may help someone out there.

hopefuly it will raise some eyebrows also!
