This code is not correct. It would only query the PKG_OPTIONS.libpurple 
variable, but the user may also set these options in 
PKG_DEFAULT_OPTIONS. The correct way to do this is:

pkgbase := libpurple
.include "../../mk/pkg-build-options.mk"

.if !empty(PKG_BUILD_OPTIONS.libpurple:Mdbus)
...
.endif
