Makefile fixes

[postmodern]

• Fixed a typo in uninstall where a .svg wasn't being `rm -f'ed.
• Install into /usr/local by default, but allow the PREFIX variable to be overridden.

Is installing to /usr/local by default recommended?

[postmodern]

/usr is reserved for software installed by the package manager, /usr/local is reserved for software installed by the system administrator. So your rpm/deb/etc specs should continue to install into /usr, but make install should definitely install into /usr/local. See the FHS for more info.

Since debian/rules and RPM spec just call make install how can the system tell the difference between an installation from a package and a manual make install?

[postmodern]

For debian/rules I have seen this done:

override_dh_auto_test-indep:

override_dh_auto_build-indep:

%:
  PREFIX=/usr dh $@

I would consult a second opinion on debian packaging etiquette, since another developer submitted the above code to one of my projects.

For rpm/*.spec I do this:

%install
make install PREFIX=%{buildroot}/usr
