[Buildroot] [PATCH v2 1/2] pkgconf: pkg-config.in: double quote $@

The shell expands "$@" as "$1" "$2" "$3"... while it expands $@ as $1 $2
$3. With the second form, we loses spaces in positional parameters.
As example, the following call
pkg-config --cflags "one two" three
is wrapped as
pkgconf --cflags one two three
while we are expecting
pkgconf --cflags "one two" three
"$@" is really useful when writing wrappers. It passes the positional
arguments *as* they are given.
Double quote $@ to prevent from splitting elements.
