Comment 1 for bug 86984

Rejecting the bug report since the problem is not in the compiler or some other ubuntu provided/supported software package, but in the scripts included with this Intel 537ep modem driver.

Specifically, it seems spaces in directory names are not taken into account properly: as a result, things went awry in the "make -C ..." command where the second argument 'SUBDIRS' contains spaces and gets misinterpreted.
Remove the spaces from the directory name "Linux ubuntu drivers" and try again.
