I got a couple of new errors since the last time cross compiled the
Linux kernel on Cygwin with 20 or so tool chains for the different
arches and compare the results to Linux
CYGWIN_NT-5.1 MediaCenterPC 1.7.0(0.212/5/3) 2009-07-24 09:59 i686 Cygwin
Linux 454util 2.6.31.5-127.fc12.x86_64 #1 SMP Sat Nov 7 21:11:14 EST
2009 x86_64 x86_64 x86_64 GNU/Linux
I'm not sure if this one is a Cygwin or make-3.81 problem, but it
centers around whether the generated executable scripts/pnmtologo.exe
has an extension of .exe or not. It it does, I get the following message
from the kernel build.

If I rename it to scripts/pnmtologo without the .exe then the build
continue on making the logo with these commands which generate
logo_linux_clut224.c from the logo file and then compile it

Here are the interesting bits of the make file
pnmtologo := scripts/pnmtologo
# Create commands like "pnmtologo -t mono -n logo_mac_mono -o ..."
quiet_cmd_logo = LOGO $@
cmd_logo = $(pnmtologo) \

-n $(notdir $(basename $<)) -o $@ $<
$(obj)/%_clut224.c: $(src)/%_clut224.ppm $(pnmtologo) FORCE
