RFR: JDK-8073328: Incremental build of gensrc broken

[Daniel Fuchs]

Hi Erik,

I tried to import your patch, and now the build fails with the
following error:

make[3]: *** No rule to make target 
`/Users/danielfuchs/workspaces/jdk/jdk9-dev-java-time/jdk/make/data/charsetmapping/stdcs-macosx', 
needed by 
`/Users/danielfuchs/workspaces/jdk/jdk9-dev-java-time/build/macosx-x86_64-normal-server-release/support/gensrc/java.base/sun/nio/cs/_the.charsetmapping-stdcs'. 
  Stop.

So it looks that something is still wrong :-(

best regards,
