Subject: [PATCH] Strip trailing space from --cflags/--libs output

pkg-config leaves a trailing space on the flags output as it may have to
do multiple iterations to collect all output and adding the space makes
concatenation simple. However, this leaves a trailing space on the full
returned string unless it's empty. Strip the trailing space after all
the processing is complete.
