[Buildroot] [git commit master] makefile: new qstrip make function

[Thomas Petazzoni]

commit: http://git.buildroot.net/buildroot/commit/?id=580c6d9b448ea8db5c9fe8f99aa43967d297903b
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Define a qstrip function that strips double quotes and then
whitespaces around a given string. This is a very commonly needed
thing, and having a function allows to remove a large quantity of
hand-written definitions, followed by a dummy comment to make text
editors not crazy because of the unmatching double quote.
