adlc is a tool that gets compiled and executed on the build host during a hotspot build. Presently it acquires the CFLAG/CXXFLAG values that are setup for compiling actual hotspot files for a target architecture. MOst of those flags are completely meaningless for the adlc build and not needed, further when cross-compiling those flags may be specific to the target architecture and would cause a build failure if used with adlc.

In 7200065 an initial workaround for this was put in place, by removing the most problmeatic flag ($ARCHFLAG) from the adlc compilation options. But the real fix is to use only those flags actually needed by adlc.
