RFR: 7200065 Cross-compilation changes to support the new-build

[Fredrik Öhrström]

The variable HOST.COMPILE.CXX points to the compiler used to create a
binary that can be
run on the build platform. But for unknown reasons it contains the standard
CFLAGS and CXXFLAGS, which are used to create the binary for the platform
where the jvm is going to be executed.

Most of these flags do not hurt the compile for the build platform (though
perhaps they are unnecessary) except the ARCHFLAG, which if not removed,
will cross compile the adlc tool.
