#98 make install does not respect "prefix=path" needed for stow

[J G Miller]

When installing the package with make, use of the syntax

make prefix="/usr/local/stow/fbpabel-{version}" install

which is respected by most major software packages, is completely ignored.

This feature is needed because when managing software installations with stow,
the actual files need to be installed under /usr/local/stow/{pacakge_name}-{version}
even though the software has been built with --prefix=/usr/local

Please correct the Makefile for the install target to respect this necessary feature.

This was tested on the latest fbpanel version 6.1 with make 3.81-7ubuntu1

[Anatoly Asviyan]

if you need sandboxed installation please use following approach
./configure --prefix=/usr/local
make
DESTDIR=/tmp/rfs/ make install
this will install files likes that
/tmp/rfs/usr/local/bin/fbpanel
and so on
