[PATCH] compat-2.6: New targets to compile bluetooth alone

[PATCH] compat-2.6: New targets to compile bluetooth alone

[Bala Shanmugam]

Compiling compat-pacakage consumes more time
as both wireless and bluetooth modules are compiled.

For someone who wants to use bluetooth alone
compiling and installing wireless modules is unnecessary
and is time consuming.

New targets are declared to compile, install, uninstall, load
and unload bluetooth modules seperately.

Usage is updated in README.
