Description of problem:
Trying to use --prefix or --relocate when installing a relocatable package does
not work.  The package always uses the default prefix in the spec file.

Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1.  Create a spec file for an rpm that is relocatable
2.  rpm -ivh --prefix=/foo file.rpm
3.  observe the package igorning the --prefix option and defaulting to the
prefix in the spec file.
	

Actual Results:  The rpm seems to install to the prefix that is defined in the
.spec file, totally ignoring the command line argument.

Expected Results:  The rpm would install to the prefix issued.

Additional info:

I can take the same package and install it on a 7.2 system.  On the 7.2 system,
the --prefix argument is followed, and my package installs to  my prefix.  Not
so on 8.0
