RFR: Bug ID: 9007227: - make/sanity-rules.gmk:61: *** multiple target patterns. Stop

[Erik Joelsson]

We identified cygwin make's inability to handle driveletter paths as one 
of the big problems with the old build system when starting the 
build-infra work for jdk8. So we designed the new build system to not 
use any mixed paths to avoid this problem. The problem with driveletter 
paths is also stated in the current README-builds.html and a number of 
workarounds are mentioned. I agree that documentation can always be 
improved however, and would encourage suggesting improvements to the 
current documentation rather than duplicating and making it redundant.
