The current mkbuildtree script uses `uname -m` when linking the
directories from the xen-sparse directory to unmodified_drivers. This
doesn't work out well if you are building 32-bit modules on a 64-bit
system.
This patch makes the architecture to be linked against a command line
option -- currently i386 or x86_64. It also cleans up the indentation a
bit.
Any comments? Better ideas?
Default to `uname -m` if no argument is provided to the script, and print a
message to explain that this is what you are doing.
Keir,
Here's an updated patch that now includes your suggestion for defaulting
to `uname -m` when no argument is passed to the script along with a
statement about defaulting.
