[microblaze-uclinux] tcl/tk bug (make xconfig) in petalinux-v0.30-rc1

[Royce Liao <modelsim62g@xxxxxxxxxxx>]

cd $PETALINUX/software/petalinux-dist
make xconfig

In Duy-Ky Nguyen's guide ("Notes on uCLinux for Spartan 3E 1500 Development Kit using EDK 9.1 and PetaLinux"), he identified a runtime script-error caused by "make xconfig."  He posted a simple workaround -- manually edit the file $PETALINUX/software/petalinux-dist/config/config.tk.

I was worried about this, because the manual-edit is a fixed-constant, and doesn't stay up-to-date, if I switch hardware-platforms.  To workaround this, I made this edit to config/config.tk:

(original text)
#set CONFIG_SYSTEM_HOSTNAME "${CONFIG_PRODUCT}" ; # <-- ERROR

to
set CONFIG_SYSTEM_HOSTNAME "$env(CONFIG_PRODUCT)"; # get shell/environment-var

This fixes the 'make xconfig' problem, and doesn't appear to break anything else, but it's still not quite optimal, because config/config.tk itself is dynamically generated by the Makefile.  Does anyone know how to 'push' this fix upstream to the source scripts (config/config.in, config/scripts/tkgen.c)?
