Since JDK-8217728, where I introduced some optimizations for handling of
the generated make dependency files for native compilation, building
hotspot incrementally on Solaris has been broken. The reason for the
breakage is that there is a clash between the *.d (header) files created
by the dtrace build and the *.d (make) files created by the compiler.
The optimization was to cat all the *.d make file together into a single
file, but if dtrace is enabled, this cat will inadvertently include the
dtrace files as well, which causes parse errors in make when make tries
to include the resulting file.
This fix changes the file extension used by dtrace files in the output
dir to *.dt to avoid the clash.
I would have changed the dependencies file - ".d" is the accepted
extension for DTrace files.
