RFR: 8361306: jdk.compiler-gendata needs to depend on java.base-launchers

[Magnus Ihse Bursie]

A recent run in the Oracle CI produced the following:

Creating ct.sym classes
/bin/bash: $WS/build/linux-aarch64-open/jdk/bin/java: No such file or directory
modules/jdk.compiler/Gendata.gmk:72: recipe for target '$WS/build/linux-aarch64-open/support/symbols/ct.sym' failed
make[3]: *** [$WS/build/linux-aarch64-open/support/symbols/ct.sym] Error 127
make[2]: *** [jdk.compiler-gendata] Error 2
make[2]: *** Waiting for unfinished jobs....
make/Main.gmk:136: recipe for target 'jdk.compiler-gendata' failed 


`jdk.compiler/Gendata.gmk` calls `$(BUILD_JAVA_SMALL)`, which is created by java.base-launchers (unless cross-compiling). This dependency is not recorded, and it has just worked due to pure luck since jdk/bin/java is usually produced much earlier in the build process.
