kbuild: make $(checker-shell ) strip spaces around the result

It looks like GNU make version 3.80 (but apparently not 3.81) adds
leading whitespace to the result of the checker-shell execution.  This
strips them off explicitly.

fix for bugzilla #7544 (keyspan USB-to-serial converter)

two different configurations, one where the input endpoints
have interrupt transfer type and one where they are bulk endpoints.
The default UHCI configuration uses the interrupt input endpoints.
The keyspan driver, OTOH, assumes that the device has only bulk
endpoints (all URBs are initialized by calling usb_fill_bulk_urb
in keyspan.c/ keyspan_setup_urb). This causes the interval field
of the input URBs to have a value of zero instead of one, which
'accidentally' worked with Linux at least up to 2.6.17.11 but
stopped to with 2.6.18, which changed the UHCI support code handling
URBs for interrupt endpoints. The patch below modifies to driver to
initialize its input URBs either as interrupt or as bulk URBs,
depending on the transfertype contained in the associated endpoint
descriptor (only tested with the default configuration) enabling
the driver to again receive data from the serial converter.
