RFR: JDK-8199103 Can't use COMPARE_BUILD with PATCH from custom root

[Erik Joelsson]

Looks good.

When looking at this patch, I realized that topdir has a different 
meaning depending on if you are in the HAS_SPEC conditional or not. In 
the first section, topdir is always the open root dir, but in the else 
section it is set to CUSTOM_ROOT if available. This is rather confusing. 
Could we unify the value of this variable?
