Maybe to have -openssl-includes= and -openssl-libs= to override the default 
openssl root relative paths?

The common way is to just have $(DESTDIR) that is added before all install 
paths.  Like in beforeauto.mk:

INSTALLBINDIR 	 := $(DESTDIR)${exec_prefix}/bin
INSTALLLIBDIR 	 := $(DESTDIR)${exec_prefix}/lib

Thus, if prefix is /usr/local, by saying "make install DESTDIR=/tmp/" would 
install everything under /tmp/usr/local/..  This way, if DESTDIR is empty, it 
does not disturb anything.

I tested it, and it is only the five variables in beforeauto.mk, plus the 
ones in idl/GNUmakefile and idl/COS/GNUmakefile.
