[9] RFR(XS) 8176238: [AOT] failure to build jdk.vm.compier with --with-jobs=1 configure flag

[Vladimir Kozlov]

https://bugs.openjdk.java.net/browse/JDK-8176238

jdk.internal.vm.compiler build fails when --with-jobs=1 is used by 
configure. Mandy suggested to add --add-modules jdk.internal.vm.ci to 
Graal annotation process command line to avoid the problem:

diff -r 932b4ec7397f make/gensrc/Gensrc-jdk.internal.vm.compiler.gmk

  PROCESSOR_PATH := $(call PathList, $(PROCESSOR_JARS))

  ADD_EXPORTS := \
+    --add-modules jdk.internal.vm.ci \
      --add-exports jdk.internal.vm.ci/jdk.vm.ci.aarch64=ALL-UNNAMED \
      --add-exports jdk.internal.vm.ci/jdk.vm.ci.amd64=ALL-UNNAMED \
      --add-exports jdk.internal.vm.ci/jdk.vm.ci.code=ALL-UNNAMED \

It works but I don't know why this happens only with --with-jobs=1.

Thanks,
Vladimir
