kbuild: add option for stripping modules while installing them
Add option for stripping modules while installing them.
This function adds support for stripping modules while they are being
installed. CONFIG_DEBUG_KERNEL (which will probably become more
popular as developers use kdump) causes the size of the installed
modules to grow by a factor of 9 or so.
Some kernel package systems solve this problem by stripping the debug
information from /lib/modules after running "make modules_install",
but that may not work for people who are installing directly into
/lib/modules --- root partitions that were sized to handle 16 megs
worth of modules may not be quite so happy with 145 megs of modules,
so the "make modules_install" never succeeds.
This patch allows such users to request modules_install to strip the
modules as they are installed.
