7141244: build-infra merge: Include $(SPEC) in makefiles and make
The build-infra project is starting to move into jdk8. For the hotspot
build to stay compatible with the changes, key hotspot makefiles need to
add an optional include statement:
In the new build system, the spec file is generated by configure and
contains the configuration for the build. Only a handfull of files need
to add this line.
In addition to including the spec file, some variables need to be
changed to only be set conditionally so that a value from the spec file
takes precedence. These are: CC, CXX, CPP, AS, MCS, STRIP, NM, NAWK (and
for windows RC and MT). The hotspot makefiles should check each variable
if it's already set or if it has a gnumake default value.
These changes have been verified to work for hotspot-rt. Jdk7u will be
verified as well before pushing.
