makefile_engine's install function fails on paths with blanks

[humdinger]

This is hrev48228.

This is from the 1st revision of the DuckSaver recipe:

INSTALL()
     mkdir -p $addOnsDir/Screen\ Savers
     make install INSTALL_DIR="$addOnsDir/Screen\\ Savers/"

This creates a package with the screensaver correctly put into "add-ons/Screen Savers/" but also results in a stray folder "add-ons/Screen\ Savers".
I tried different escaping, removing the quotes etc., with no success. I finally did the same work around I've seen in another screen saver recipe:

make install INSTALL_DIR=temp
mv temp/DuckSaver $addOnsDir/Screen\ Savers

So... ​makefile_engine or haikuporter to blame? (or me? :))

Fixed in hrev52738.

The fix resulted in filenames with spaces to appear 'escaped': , e.g. "Open Origin Package" becomes "Open\ Origin\ Package", see ​https://github.com/haikuports/haikuports/pull/3580

Re-fixed properly in hrev52792.
